Commercial door hardware is specified in CSI MasterFormat Division 8 (Openings), specifically Section 08 71 00 (formerly Section 08710). Hardware is organized into numbered hardware groups (or sets) that list every component for each door type: hinges, lockset, closer, stop, seals, thresholds, and specialty items. The door schedule on the architectural drawings assigns each door to a hardware group. The keying schedule (developed separately at a keying conference) defines the master key hierarchy for every lockable door. The hardware submittal is prepared by the hardware distributor, reviewed by the architect or AHC, and returns as Approved, Approved as Noted, Revise and Resubmit, or Rejected. Substitutions go through Division 01 Section 01 25 13 procedures with the CSI Substitution Request Form. Errors between the door schedule and hardware specification are the most common source of change orders on commercial hardware projects.
The Division 8 specification process is where security intentions become actual hardware on actual doors. An architect's vision for building security is only as good as the hardware specification that translates it into purchase orders. A facility manager who inherits a building without understanding how the hardware was specified cannot effectively plan for maintenance, replacement, or upgrades. And a contractor who doesn't understand the submittal process will generate avoidable change orders, delays, and rework. This guide covers every layer of the process from specification structure through delivery.

How CSI Division 8 Is Organized
The Construction Specifications Institute (CSI) MasterFormat divides a project's construction specifications into divisions by trade and product category. Division 8, titled Openings, covers everything related to building openings: doors, frames, windows, curtain walls, hardware, and glazing. Each product category within Division 8 has its own section number, and every section follows the same three-part structure (General, Products, Execution) that contractors, distributors, and architects have used for decades.
| Section | Title | Relevance to Hardware |
|---|---|---|
| 08 11 00 | Metal Doors and Frames | Defines hollow metal door and frame specifications; hardware prep requirements for frames |
| 08 14 00 | Wood Doors | Covers architectural flush wood doors; hardware blocking and factory prep requirements |
| 08 41 00 | Entrances and Storefronts | Aluminum entrance systems; hardware integration with storefront framing |
| 08 71 00 | Door Hardware | Primary hardware specification section: hinges, locks, closers, exits, seals, all finish hardware |
| 08 80 00 | Glazing | Glass types and performance for vision panels and glazed openings |
| 08 31 00 | Access Doors and Panels | Mechanical, electrical, plumbing access doors; typically separate from finish hardware |
The old numbering system (08710, 08711, etc.) and the current six-digit numbering (08 71 00) refer to the same content. Older project manuals and many institutional owner standards still use the old format. Both formats follow identical organization; only the section numbering differs.
Section 08 71 00 Structure: What the Three Parts Cover
Part 1: General
Part 1 covers the administrative and procedural requirements for the hardware specification. Key elements include: the AHC qualification requirement (many specifications require the hardware supplier to employ a current Architectural Hardware Consultant available during the project); submittal requirements and format; delivery, storage, and protection requirements; coordination requirements with other divisions; and the keying conference requirement. Part 1 also sets out source limitations: most institutional specifications require that each type of hardware (all locksets, all closers, all exit devices) come from a single manufacturer, not mixed brands within a hardware group.
Part 2: Products
Part 2 defines the specific hardware products: manufacturers, product series, material standards (ANSI/BHMA grades), finishes, and function codes. This is where hardware groups are defined. Each group lists every component with its manufacturer's catalog number, ANSI/BHMA grade, finish (in ANSI/BHMA finish code format), and any special requirements (fire rating, electrification, cylinder type).
Part 3: Execution
Part 3 covers installation: mounting heights for each hardware type, adjustment requirements, field verification, and closeout requirements including delivery of keys to the owner and submission of as-built hardware schedules.
Hardware Groups: How Door Hardware Is Organized in the Specification
The hardware group (also called a hardware set) is the core organizational unit of Section 08 71 00. It is a numbered list of every hardware item required for a specific door type. Groups are numbered sequentially; all doors assigned to the same group receive identical hardware.
How Hardware Groups Are Assigned
The AHC or hardware consultant assigns hardware groups based on each door's function, location, fire rating, occupancy requirements, security level, and expected traffic volume. Two doors that appear identical on the floor plan may use different hardware groups if one is on a fire-rated wall and the other is not, or if one requires an electrified lockset for access control integration.
Grouping logic typically follows this pattern: doors with the same function, same fire rating, same finish, and same security level share a hardware group. Changes in any of those variables create a new group. On a large project with 300 doors, there may be 20 to 40 hardware groups covering all door types.
The Door Schedule: Bridge Between Drawings and Specification
The door schedule is a tabular document on the architectural drawings (typically on the finish schedule or door/window schedule sheet) that lists every opening on the project with its complete identifying information. Each row is one opening. The columns typically include: door number, floor level, opening size (width and height), door material and gauge, frame material and profile, fire rating, hardware group designation, glazing requirements, and special notes.
Reading a door schedule entry works like this: Door 201 / Floor 2 / 3'-0" x 7'-0" / HM 18 gauge / HM KD frame / 90-minute / HW-7 / None / Pair, closer on pull side. The hardware distributor reads door 201 as a 90-minute pair, orders the hardware specified in Group HW-7, and confirms that the fire-rated group includes pair-compatible hardware (coordinator, active leaf flush bolts if specified, or constant-latching flush bolts per NFPA 80 healthcare requirements).
On large projects, door schedules contain hundreds or thousands of rows. Conflicts between the door schedule and the hardware specification are among the most common sources of project delays and change orders. The most frequent conflicts: a door schedule assigns a fire-rated door to a non-fire-rated hardware group; a door schedule shows a pair but the hardware group specifies single-door hardware; or a door schedule shows an electrified opening but the hardware group has no power transfer provision.
The Keying Schedule and the Keying Conference
The keying schedule is a separate document from the hardware specification and the door schedule, but it must be coordinated with both. It defines the complete master key hierarchy for the project and assigns every lockable door to a specific change key, master key group, and level of the keying system.
The keying conference is a meeting between the hardware distributor, the building owner (or owner's representative), and often a locksmith or security consultant. It typically occurs during the submittal phase after the hardware submittal is approved. The keying conference produces three outcomes: the agreed master key hierarchy (levels, groups, and the organizational logic behind them); the keyed-alike and keyed-different assignments for every door; and the key quantity required for each level.
What the Keying Schedule Must Include
A complete keying schedule lists each door number, the lock function at that opening, the change key designation, which master key(s) open it, and any special keying requirements (keyed alike with another opening, cross-keyed, or master keyed only). For projects using SFIC (Small Format Interchangeable Core) cylinders, the keying schedule also identifies the control key hierarchy and the core changeover plan from construction keys to permanent keys.
Most specifications require the hardware distributor to submit the keying schedule for architect and owner approval before ordering cylinders. Cylinders cut to an incorrect keying arrangement cannot be corrected without replacing the cylinder or repinning. Keying errors discovered after installation are expensive corrections.

The Hardware Submittal Process
Hardware distributor prepares submittal package
The distributor compiles a complete submittal: every hardware item organized by group, with manufacturer, model number, catalog reference, finish, function code, and ANSI/BHMA grade. Product data sheets for each item. Grade certifications. Finish samples if required by the specification. A marked-up copy of the hardware schedule showing any proposed substitutions clearly noted as such. The keying schedule if ready. Point-to-point wiring diagrams for electrified hardware.
General contractor reviews and stamps
The GC reviews the submittal for completeness and stamps it with their subcontractor coordination review before forwarding to the architect. GC review is an administrative check, not a technical hardware review. The GC's stamp confirms the submittal has been reviewed by the contractor, not that the hardware is correct.
Architect or AHC reviews for specification conformance
The architect (or the AHC acting as the architect's agent) reviews each item against the specification requirements. Grade, function, finish, and any special requirements are checked against Part 2 of the hardware specification. Any substitutions are checked against the substitution request format and evaluated for equality. Comments and status are marked on each item.
Submittal returns with review status on each item
The reviewed submittal returns to the distributor via the GC. Each item carries one of four review statuses. Items marked Revise and Resubmit or Rejected must be corrected and resubmitted before materials can be ordered. Items marked Approved or Approved as Noted can proceed to order.
The Four Submittal Review Statuses
Approved
Supply exactly as submitted. No changes required. The specified product was submitted and confirmed.
Approved as Noted
Supply with the noted corrections. Corrections are minor (finish code revision, function number typo, quantity adjustment). No resubmittal required unless the notes include significant changes.
Revise and Resubmit
Does not meet specification requirements as submitted. Submit a corrected alternative for review. Common for: wrong ANSI grade, wrong finish, wrong function, or substitution without a formal substitution request.
Rejected
Does not comply and a substitution is not acceptable. Provide the specified product. Used when a substitution request was submitted and denied, or when the submitted product is fundamentally non-compliant.
Hardware Substitutions: Division 01 Section 01 25 13
A substitution is a request to provide a product different from what was specified by the architect. The substitution procedure is not in Section 08 71 00. It is defined in Division 01 of the project manual, typically Section 01 25 13 (Product Substitution Procedures). Submitting a proposed alternative as if it were the specified product, without a formal substitution request, will generate a Revise and Resubmit status at minimum and a Rejected status if the reviewer recognizes the product does not match.
What a Valid Substitution Request Requires
The CSI Substitution Request Form is the standard vehicle. A complete substitution request includes: the specified product (manufacturer, model, specification reference); the proposed substitute (manufacturer, model, catalog reference); a point-by-point comparison demonstrating that the substitute meets the same performance grade, function, application, aesthetic, and quality as the specified product; documentation of any differences and why they do not affect performance; and the reason the specified product cannot be provided (typically discontinued, long lead time, or pricing).
Fire-Rated Opening Coordination in Section 08 71 00
Fire-rated openings are the most regulated and highest-risk element of a hardware specification. Every component on a fire-rated opening must be part of a tested and listed assembly, and the authority having jurisdiction (AHJ) can require replacement of any component that does not match the listing, even if the substitution appears functionally identical.
| Fire Rating | Typical Application | Hardware Requirements |
|---|---|---|
| 20 min | Corridor walls, tenant separation, some interior walls | Self-latching, UL listed hardware; closers not always required |
| 45 min | 3/4-hour openings in 1-hour separations; stairwells in some occupancies | Self-closing and self-latching; listed hinges; listed closer |
| 60 min | Horizontal exits, 1-hour occupancy separations | Self-closing, self-latching, positive latch; all hardware UL listed for 1-hour |
| 90 min | Stairwell enclosures in 2-hour construction, exit enclosures | Self-closing, self-latching, positive latch; all hardware UL listed for 90 min; no glazing limitations for some assemblies |
| 180 min | Fire walls, building separations | Most restrictive hardware requirements; limited trim options; all hardware must match listed assembly |
The Change Order Risks That Fire-Rated Openings Create
Hardware group assigned to wrong fire rating
The most common specification error: a 90-minute fire door is assigned to hardware group HW-3, which was written for non-fire-rated interior doors. The group does not include a door closer, NRP hinges, or smoke gasketing. Caught during submittal review, it adds two to three weeks for revision and resubmission. Caught in the field during installation inspection, it adds three to six weeks for correction and replacement hardware sourcing.
Non-listed hardware substituted on fire-rated opening
A hardware distributor substitutes a cylindrical lockset from a manufacturer not listed for that specific fire door assembly, or a closer from a manufacturer whose listing does not cover the door width. The AHJ inspects and requires replacement with listed hardware. Replacement cost: full hardware package for the affected doors plus installation labor.
Pairs of fire doors without proper coordinators or flush bolts
Pairs of fire doors require coordinators (to ensure the inactive leaf closes before the active leaf) and constant-latching flush bolts on the inactive leaf. Hardware groups that specify single-door hardware for a pair opening, or that omit the coordinator when one is required by the fire door listing, generate field corrections and reinspections.
Door closer specification not matching fire rating requirement
A door closer specified for a fire-rated opening must carry UL 10C Positive Pressure listing. A closer that is ANSI/BHMA Grade 1 but lacks UL 10C cannot be used on a fire-labeled door assembly regardless of its mechanical performance rating. Hardware groups that specify a closer by grade only without confirming UL 10C listing create field corrections.

What the AHC Designation Means and When It Matters
The Architectural Hardware Consultant (AHC) designation is awarded by the Door and Hardware Institute (DHI) and has existed since 1940. It certifies that the holder has demonstrated mastery in commercial door hardware product application, code integration (fire, life safety, ADA accessibility), and professional specification writing. The AHC exam tests knowledge across all hardware categories, all relevant codes (IBC, NFPA 80, NFPA 101, ADA, ANSI/BHMA standards), and the specification and submittal processes described in this guide.
Many Division 8 specifications include a qualification requirement stating that the hardware distributor must employ or have available an AHC during the project. This means the distributor submitting the hardware bid and preparing the hardware submittal must have a current AHC on staff or retained. When a contractor receives a specification with this requirement, they should verify AHC status with the hardware distributor before awarding the hardware subcontract. A hardware submittal prepared without AHC involvement on a project that requires it may be returned for resubmission at the contractor's expense.

Why Choose Security Parts for Division 8 Project Parts
Fire-rated group assignment error documentation, or-equal substitution rejection mechanism explained, keying conference deliverables, AHC qualification requirement, and same-day OEM shipping.
Fire Group Assignment Error
We document that assigning fire-rated and non-fire-rated doors to the same hardware group is the single most common hardware specification error, and the specific change order cost it generates at each stage when discovered (submittal vs field inspection). No competitor documents this at the parts level.
Or-Equal Substitution Reality
We document why Grade 1 certification alone does not make a product an approved equal when the specification product exceeds minimum standards. This is the most common substitution rejection reason and is not explained in competitor content.
Keying Conference Deliverables
We document the three specific deliverables the keying conference must produce: the agreed master key hierarchy, the keyed-alike/keyed-different assignments, and the key quantities. Missing any deliverable creates keying errors discovered after installation.
Same-Day OEM Shipping
OEM parts from Schlage, Von Duprin, LCN, and Falcon ship same day for all Division 8 specified products. Call 845-935-0301 or the contact page for specification support.
What Makes Security Parts Different for Division 8 Project Hardware Parts
- We document the specific change order cost timeline for the most common hardware specification error (fire-rated vs non-fire-rated doors in the same hardware group) at two stages: caught during submittal review (two to three weeks for revision) and caught in the field during inspection (three to six weeks). Giving contractors the cost of catching it late creates urgency to verify before submitting.
- We document why "or equal" does not mean "meets Grade 1 minimum" on projects where the specified product exceeds the minimum standard. The architect's product choice often encodes requirements beyond the minimum that a CSI substitution request must demonstrate, not just assert.
- We document the three specific keying conference deliverables that must be completed before cylinders can be ordered, and what happens to project schedule when the keying conference is delayed because the building owner has not made access control decisions.
- We document the UL 10C Positive Pressure listing requirement for door closers on fire-rated assemblies as distinct from ANSI/BHMA Grade 1 mechanical certification. A Grade 1 closer without UL 10C fails fire-rated opening requirements. This distinction is missed in most competitor hardware content.
- We carry Schlage ND Series cylindrical lock parts, Schlage L Series mortise lock parts, Von Duprin exit device parts, and LCN door closer parts for all Division 8 hardware categories as authorized Allegion OEM parts.
- Free shipping on orders over $450. Same-day shipping from US warehouses on stocked parts. 30-plus years of commercial door hardware experience.
Frequently Asked Questions About Division 8 Door Hardware Specification
What is CSI Division 8 and what does Section 08 71 00 cover?
CSI MasterFormat Division 8 (Openings) covers all door, frame, hardware, glazing, and related components in commercial construction. Section 08 71 00 (Door Hardware, formerly 08710) is the specific section specifying all finish hardware: hinges, locksets, exit devices, door closers, stops, seals, and specialty items. It is organized in three parts: General (qualifications, submittals, delivery), Products (specifications and hardware groups), and Execution (installation, adjustment, closeout). It forms the contractual basis for all hardware on the project.
What is a hardware group (hardware set) in a door specification?
A hardware group is a numbered list of every hardware component required for a specific door type. Groups are numbered sequentially (HW-1, HW-2, etc.) and include every item: hinges, lockset, closer, stop, seals, threshold, silencer, and specialty items. Every door on the project is assigned to a hardware group in the door schedule; all doors with the same group number receive identical hardware. The group is the specification's complete answer to: what hardware does this door get?
What is the difference between the door schedule and the hardware specification?
The door schedule is a tabular drawing document listing every door with its size, material, fire rating, and assigned hardware group number. The hardware specification (Section 08 71 00) in the project manual defines what is in each group. They work together: the door schedule tells you which group each door uses; the specification tells you what that group contains. Conflicts between the two documents are the most common source of hardware project change orders. The fire rating column in the door schedule vs the fire-rated requirements in the hardware group is the most frequent conflict point.
How does the hardware submittal process work?
The hardware distributor prepares a submittal package listing every hardware item by group with manufacturer, model, finish, function, and any substitutions. The general contractor reviews and stamps it, then forwards it to the architect. The architect or AHC reviews each item against the specification and returns it marked Approved, Approved as Noted, Revise and Resubmit, or Rejected. Items marked Revise and Resubmit or Rejected must be corrected and resubmitted. Materials can only be ordered after items are Approved or Approved as Noted.
What is the substitution procedure for door hardware and how is it handled?
Substitutions go through Division 01 Section 01 25 13 (Product Substitution Procedures), not Section 08 71 00. A valid substitution request uses the CSI Substitution Request Form with a point-by-point comparison showing the substitute meets the same grade, function, aesthetic, and quality as the specified product. The architect judges whether a substitution is an approved equal. Meeting ANSI/BHMA minimum Grade 1 is not sufficient if the specified product exceeds the minimum standard in ways the substitution does not match.
What is an Architectural Hardware Consultant (AHC) and when is one required?
The AHC is a professional certified by the Door and Hardware Institute (DHI) since 1940 in commercial hardware specification, code compliance, and project coordination. The AHC validates mastery in product application, fire/life safety/ADA code integration, and specification writing. Many Division 8 specifications require the hardware supplier to employ a current AHC during the project and that the hardware schedule be prepared under AHC supervision. Contractors should verify AHC status with their hardware distributor before award on any project that includes this requirement.
