Trusted Since 2001
Security Parts carries the complete range of Schlage and Falcon strike plates, deadlatches, and latch bolt combinations. Strike plates in the 10-series include the 10-094 flat square-corner strike (B Series standard), the 10-087 ANSI strike with dust box (B600/700 Grade 1 applications), the 10-092 full lip round corner (Falcon B700 standard), the 10-095 full lip square corner, and the Falcon 10-064 circular thimble drive-in. Deadlatches include the 16-228 (square corner, L Series and cylindrical) and 16-260 (dual option). Latch bolt combinations include the 12-339 dual option combination (CS210 and B Series), the 16-483 fixed square corner combination, and the 16-484 large combination with 5-inch backset option. The 12-340 is the adjustable bolt for L Series and CS210 applications.
Strike plates and latch bolts are the most frequently ordered individual parts on any commercial door hardware service call. They are also the most frequently mis-ordered. A strike that is the wrong corner style leaves visible gaps in the frame. A latch bolt with the wrong backset will not engage the strike. A deadlatch specified where a spring latch was installed fails to provide the deadlocking protection the facility expects. Getting these parts right requires knowing which lock series they serve, what the existing frame mortise requires, and whether a box, thimble, or standard flat plate is appropriate for the door frame material.

Strike Plates: The Most Misunderstood Door Hardware Component
A strike plate is the metal fitting mounted in the door frame that receives the lock's latch bolt or deadbolt when the door closes. It sounds simple, and it is mechanically. But the number of variables in strike plate selection produces more wrong orders and more callbacks than almost any other single door hardware part. Understanding these variables before ordering eliminates most strike plate service calls.
The four variables that determine the correct strike plate are: the lock series (which determines the bolt dimensions), the corner style of the existing frame mortise (square corner or round corner), the frame material (hollow metal requiring a dust box or wood accepting either), and whether a full lip, flat, or thimble profile is needed for the specific application.
Square Corner vs Round Corner: The First Decision
The corner style describes the shape of the strike plate faceplate corners where the plate sits flush in the door frame. This is not a preference or aesthetic choice. It is determined by the shape of the existing mortise pocket in the door frame, which was cut at the time of original installation and cannot be changed without additional frame work.
Square corner (90-degree straight corners) is standard for hollow metal door frames in commercial construction and for most modern wood frame installations that used a chiseled or milled square mortise. The vast majority of commercial and institutional door installations use square corner strikes.
Round corner (typically 1/4-inch radius) is found on older wood frame installations where the mortise pocket was routed with a router bit that leaves curved corners, and on installations that specifically called for round corner strikes in the original specification. Round corner strikes are less common in commercial construction but remain in widespread use in renovation and repair work on older buildings.
Dust Box vs No-Box Strikes: Frame Material Determines the Choice
A dust box is the metal enclosure that mounts behind the strike plate face and extends into the door frame, creating a protected cavity that receives the latch or deadbolt. The name comes from the box's original purpose of protecting the bolt pocket from paint, debris, and moisture that would otherwise accumulate in an open frame mortise pocket.
For hollow metal door frames in commercial applications, a dust box is required on every strike plate. The metal frame provides no natural wood pocket for the bolt: without a box, the bolt would enter an empty void in the metal frame with nothing to contain or guide it. The dust box creates the pocket the bolt needs to engage reliably on every door closure.
For solid wood door frames, a dust box is not strictly required because the wood provides its own pocket around the mortise. However, box strikes are preferred on wood frames for two reasons: the box prevents wood shrinkage from closing the pocket over time (especially in climates with significant seasonal humidity variation), and the box prevents moisture and paint from accumulating in the pocket on painted frames. The no-box strike is acceptable on interior wood frame applications with low moisture exposure.
Full Lip vs Flat Strikes: When the Frame Dimension Matters
A full lip strike has an extended plate section (the "lip") that projects beyond the strike face onto the door stop surface of the frame. The lip covers the gap between the door face and the frame face, providing additional protection against latch shimming attacks (using a card or thin tool to push the latch back through the gap between door and frame).
A flat strike (no-lip or short-lip) sits flush in the frame face mortise without the extended projection. Flat strikes are used where the door stop geometry does not permit a full lip or where the specification does not require the additional shimming protection.
For commercial security applications, full lip strikes provide better resistance to shimming attacks and are preferred on exterior and secured interior doors. Flat or short-lip strikes are appropriate for interior doors where latch shimming is not a security concern.
Schlage Strike Plate Products at Security Parts
Schlage 10-094
Standard flat square corner deadbolt strike for B Series B500 and B600 applications and Falcon cylindrical applications. 1-1/8 inch by 2-3/4 inch. No dust box. Used on wood frames and in repair applications where the original pocket accommodates a no-box strike. Template J884 (wood jamb). Current production does not include a box; prior versions did. Confirm frame material before ordering.
Schlage 10-087
ANSI-specification strike plate with dust box for B600 and B700 Grade 1 deadbolts and high-security applications. 1-1/4 inch by 4-7/8 inch provides larger frame coverage and a deeper bolt pocket than the standard 10-094. The larger ANSI footprint increases kick-in resistance by spreading the bolt load across more frame material. Template J918 (wood jamb), J919 (metal jamb). Standard for Grade 1 commercial entries.
Schlage 10-116
Round corner deadbolt strike, 1-1/8 inch by 2-3/4 inch, no lip, no box. Used when the frame mortise has 1/4-inch radius corners. Most commonly found on older residential and light commercial wood frame installations. Also specified as the round-corner option for CS210 deadbolt strike when the frame mortise was originally cut with a round-corner template.
Falcon Strike Plates at Security Parts
Falcon 10-064
Circular (thimble) drive-in strike for Falcon and Schlage B600/700 Series deadbolts on narrow frame or aluminum frame applications. Installed by driving into a pre-bored hole in the frame edge rather than mortising a flat pocket in the frame face. The thimble format is the correct choice for aluminum storefront frames where the frame stile is too narrow for a standard flat strike plate. Template J563. Also used where a flush, hidden strike is preferred for aesthetic reasons.
Falcon 10-087
ANSI strike with plastic dust box for Falcon B600/700 and Schlage applications. 4-7/8 inch by 1-1/4 inch, 1-3/16 inch lip to center. Plastic box version as noted in part number 10-087. Identical footprint to the Schlage 10-087 ANSI specification. Used on Grade 1 applications requiring ANSI strike dimensions with box protection. Template J918 wood jamb, J919 metal jamb.
Falcon 10-092
Full lip round corner strike, 2-1/4 inch by 1-5/8 inch, 1-1/8 inch lip, 1/4-inch radius corners. No box. Used on Falcon cylindrical locks and Schlage cylindrical applications where a full lip provides shimming protection and the frame has round-corner mortise pockets. Template J786. The full lip covers the gap between door and frame, eliminating the shimming attack vector on spring latch cylindrical locks.
Falcon 10-095
Full lip square corner strike, 2-1/4 inch by 1-5/8 inch, 1-1/8 inch lip. No box. Same dimensions as the 10-092 but with square corners. Used on square-corner frame mortises that require full lip coverage. Template J787. The square corner version covers the majority of commercial cylindrical lock applications where full lip shimming protection is required on hollow metal frames.

Schlage Deadlatches: 16-228 and 16-260
A deadlatch is a spring-operated latch bolt that incorporates an automatic deadlocking mechanism. Standard spring latches can be manipulated back into the door with a thin card or tool inserted between the door edge and the frame. A deadlatch prevents this: a small plunger (the deadlocking plunger) extends alongside the main latch bolt when the door closes. When this plunger contacts the strike plate face, it locks the latch bolt in the extended position, preventing the bolt from being pushed back without operating the lever from inside or the key from outside.
Schlage 16-228: Standard Deadlatch
The Schlage 16-228 is a square corner deadlatch with a 1-1/8 inch by 2-1/4 inch faceplate. It is the standard deadlatch replacement for Schlage L Series mortise locks and cylindrical lock applications where square corner frame prep exists. The 16-228 is a fixed square-corner configuration, suitable for hollow metal frame installations and wood frame installations with square-corner mortise pockets.
Schlage 16-260: Dual Option Deadlatch
The Schlage 16-260 is the dual option deadlatch: it includes both square and round corner faceplates in the same package, along with a 1-inch by 2-1/4-inch faceplate dimension. The dual option design means one part number covers more installation scenarios, reducing the need to correctly identify corner style before ordering. On a renovation project where the existing frame corner style is uncertain or inconsistent across multiple doors, the 16-260 eliminates the risk of ordering the wrong corner style.
Schlage Latch Bolt Combinations: 12-339, 16-483, 16-484
Latch bolt combinations package both a deadbolt and a deadlatch in a single assembly for applications where both are required and pre-matched components are preferred over sourcing separately.
Schlage 12-339: Dual Option Deadbolt/Deadlatch Combination
The Schlage 12-339 is a 1-inch by 2-1/4-inch dual option combination containing both a deadbolt and a deadlatch. Dual option means both square and round corner faceplates are included. The 12-339 fits standard 2-3/8-inch or 2-3/4-inch backsets. It is used in the Schlage CS210 interconnected lock as the complete latch assembly replacement and in B Series and related applications where a matched combination ensures the deadbolt and latch have identical faceplate dimensions and compatible backsets.
The 12-340 is the adjustable bolt variant: a 1-inch by 2-1/4-inch square corner deadbolt only (not a combination) that adjusts for both 2-3/8-inch and 2-3/4-inch backsets. It is used in Schlage L Series mortise locks and CS210 applications where only the deadbolt requires replacement rather than the full combination.
Schlage 16-483: Fixed Square Corner Combination
The Schlage 16-483 is a square corner deadbolt/deadlatch combination with 1-1/8 inch by 2-1/4 inch faceplates. Where the 12-339 is dual option (both corner styles included), the 16-483 provides fixed square corner configuration. It is used when the frame prep is confirmed as square corner and the larger 1-1/8-inch faceplate width is preferred over the 1-inch width of the 12-339.
Schlage 16-484: Large Combination with 5-Inch Backset Option
The Schlage 16-484 is a square corner deadbolt/deadlatch combination with 1-inch by 2-1/4 inch faceplates and an optional 5-inch backset configuration. The 5-inch backset option is used on doors where the bore preparation is set further back from the door edge than the standard 2-3/8-inch or 2-3/4-inch backsets. This is most common on glass door applications where the bore must clear the glass panel edge, and on wide-stile commercial doors where hardware aesthetics require a further setback from the door edge.
Schlage 16-132: 5-Inch Backset Deadlatch
The Schlage 16-132 is a square corner deadlatch with a 1-1/8 inch by 2-1/4 inch faceplate specifically for the 5-inch backset configuration. It is used on the same applications as the 16-484's 5-inch backset option but when only the deadlatch (not the combination) requires replacement. The 16-228 and 16-260 cover standard 2-3/8-inch and 2-3/4-inch backsets; the 16-132 specifically addresses the 5-inch backset requirement.
What is a Deadlatch vs a Deadbolt vs a Spring Latch?
These three terms are frequently confused and the confusion generates mis-ordered parts. Understanding the distinction prevents returning the wrong part.
| Bolt Type | How It Works | Auto-Locks? | Requires Key to Open? | Example Parts |
|---|---|---|---|---|
| Spring latch | Spring-loaded bolt that retracts when lever is turned; can be shimmed back | No | No (lever only) | THP-8201, standard cylindrical latch |
| Deadlatch | Spring-loaded bolt with deadlocking plunger; cannot be shimmed when plunger contacts strike | Yes (auto) | No (lever only from inside) | 16-228, 16-260, THP-8219 |
| Deadbolt | Manually thrown bolt with full 1-inch throw; not spring loaded | No (manual) | Yes (key or thumbturn) | B500, B600, 12-340 bolt |
| Combination | Both deadbolt and deadlatch in matched set | Partial (deadlatch auto) | Partially (deadbolt requires key) | 12-339, 16-483, 16-484 |
How to Identify the Correct Strike or Latch Before Ordering
Three measurements and two observations determine the correct part for any strike or latch replacement.
1. Bolt or latch body dimensions (width x length of faceplate). Remove the existing strike or latch and measure the faceplate. The most common commercial dimensions are 1-1/8 inch by 2-1/4 inch (latch bolts and combination faceplates) and 1-1/8 inch by 2-3/4 inch (deadbolt strikes).
2. Backset (for latches). Measure from the door edge to the center of the bolt bore, with the bolt removed. Standard backsets are 2-3/8 inch and 2-3/4 inch. The 5-inch backset is a specialty configuration.
3. Corner style (for strikes). Observe the existing frame mortise pocket corners. Square equals 90-degree straight corners. Round equals 1/4-inch radius curved corners.
4. Frame material (for strikes). Hollow metal frame requires a dust box strike. Wood frame accepts either box or no-box.
5. Bolt type (for latches). Does the existing latch have a small secondary plunger alongside the main bolt? If yes, it is a deadlatch and requires a deadlatch replacement. If the bolt is a single simple spring bolt, it is a standard spring latch.

Why Choose Security Parts for Strike Plates and Latch Bolt Parts
Frame material guidance, deadlatch replacement warning, paint-filled pocket diagnosis, corner mismatch prevention, and same-day shipping on stocked parts.
Deadlatch Replacement Warning
We document that replacing a deadlatch with a spring latch eliminates deadlocking protection without any visible change in door operation. This is the most common undetected security downgrade in commercial buildings.
Corner Mismatch Prevention
We document that the existing mortise pocket shape determines the corner style, not the existing strike. Ordering by the existing strike's corner style when the pocket has been re-cut produces a gap-fitting replacement.
Deadlocking Plunger Fact
We document the deadlocking plunger contact requirement: a deadlatch only deadlocks when the plunger contacts the strike face. A misaligned strike that allows the latch to enter the pocket without plunger contact leaves the door unlocked.
Same-Day Shipping
Most strike plates and latch bolts ship same day from US warehouses. Call 845-935-0301 or use the contact page for corner style and bolt type confirmation support.
What Makes SecurityParts.com Different for Strike Plates and Latch Bolts
- We document the spring latch to deadlatch downgrade: replacing a 16-228 or 16-260 deadlatch with a standard spring latch removes deadlocking protection invisibly. This security vulnerability is never documented at the parts ordering stage by any competitor.
- We document the deadlocking plunger contact requirement. A perfectly functioning deadlatch that does not contact the strike face does not deadlock. Strike alignment is a prerequisite for deadlatch function that is never explained in competitor parts content.
- We document that the 10-094 current production no longer includes a box, while prior versions did. Ordering the 10-094 for a hollow metal frame application where the previous version included a box will produce a no-box replacement that requires additional frame work.
- We document that the ANSI strike (10-087) is not just a larger version of the 10-094: it addresses a different security level (Grade 1 B600/700 vs Grade 2 B500) with a larger force-distribution footprint for improved kick-in resistance.
- We carry strike plates and latch bolts alongside B Series deadbolt parts, L Series mortise lock parts, cylindrical lock parts, LCN door closer parts, and exit device parts for complete door hardware service in one order.
- 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 Schlage and Falcon Strike Plates and Deadlatches
What is the difference between a square corner and round corner strike plate?
Square corner means the faceplate has 90-degree straight corners. Round corner means the corners have a 1/4-inch radius curve. The frame mortise pocket shape determines which is needed: the strike must match the pocket. Square corner is standard for commercial hollow metal frames. Round corner is found on older wood frame installations with routed mortise pockets. Using the wrong corner style leaves visible gaps between the strike face and the frame.
What is the difference between a strike plate with a dust box and one without?
A dust box creates a protected metal pocket behind the strike face that receives the bolt. It is required for hollow metal frames that have no natural wood pocket for the bolt. No-box strikes rely on the frame material's own mortise pocket and are used on wood frames. On commercial hollow metal frame applications, always specify a box strike. The 10-087 ANSI strike with box is the correct Grade 1 commercial standard; the 10-094 (no box) is used for Grade 2 wood frame applications.
What is a Schlage 16-228 deadlatch and when is it used?
The 16-228 is a square corner deadlatch with a 1-1/8 inch by 2-1/4 inch faceplate for Schlage L Series mortise locks and cylindrical lock applications. A deadlatch adds a secondary plunger that prevents the bolt from being shimmed back when the plunger contacts the strike face. It provides security beyond a spring latch without requiring a deadbolt. The 16-260 is the dual option version with both square and round corner faceplates included.
What is the Schlage 12-339 deadbolt/deadlatch combination and what lock series does it fit?
The 12-339 is a dual option combination assembly containing both a deadbolt and a deadlatch. It fits 2-3/8-inch and 2-3/4-inch backsets and is used in the CS210 interconnected lock and B Series applications where a pre-matched combination simplifies replacement. The 16-483 is the fixed square corner version; the 16-484 includes a 5-inch backset option. The 12-340 is the adjustable deadbolt only (no latch) for L Series and CS210 deadbolt-only replacement.
What is the Falcon 10-064 circular drive-in thimble strike?
The 10-064 is a circular thimble strike driven into a pre-bored hole in the door frame edge rather than mortised in the frame face. It is used for narrow aluminum and steel frames where standard flat strike plates do not fit, and for applications where a hidden strike appearance is preferred. Template J563. Specified on aluminum storefront frame applications where the frame stile is too narrow for the 10-094 or 10-087.
What is an ANSI strike and when is the Schlage 10-087 used instead of the 10-094?
The 10-087 is the ANSI-specification strike (1-1/4 inch by 4-7/8 inch with dust box) for Grade 1 B600/700 deadbolts. The larger footprint distributes bolt load across more frame material, increasing kick-in resistance. The 10-094 (1-1/8 inch by 2-3/4 inch, no box) is the standard for Grade 2 B500 applications. Use the 10-087 when the specification requires ANSI/BHMA A156.31 strike dimensions or when Grade 1 security level is required. Templates J918 (wood) and J919 (metal).
