Security Parts carries parts for the Schlage CL Series cabinet locks and HL6 Series hospital latch locks. CL Series parts include the CL10-301 cylinder retaining screw, CL10-350 adapter spacer, CL10-352 slotted strike, CL10-354 bar strike (1/4 inch thick), CL10-355 bar strike (1/2 inch thick), and Schlage 36-031 trim collar. HL6 Series parts include the HL6 mortise paddle assembly, HL6 tubular paddle assembly, cover assembly, and bent tab mortise strike kit in engraved and non-engraved configurations. The HL6 uses the Schlage L Series mortise chassis. Mortise cylinders and housings are ordered separately from HL6 latches.

Two of the most specialized product categories in commercial door hardware sit in the same part of the SecurityParts.com catalog: Schlage CL Series cabinet locks and Schlage HL6 Series hospital latch locks. They serve completely different applications, but they share a common characteristic: almost every buyer who needs a replacement part struggles to find accurate technical information before ordering. Cabinet lock parts are rarely documented beyond a part number. Hospital latch parts carry healthcare-specific features like anti-barricade key override and lead lining that are absent from most parts supplier content.

Schlage CL Series Cabinet Locks: What They Are and Why They Exist

The Schlage CL Series is a cabinet lock line built around the same full-size Schlage cylinders used in commercial door hardware, rather than the smaller wafer-based or cam-type cylinders common in most office furniture locks. This is the design decision that makes the CL Series different from every other cabinet lock on the market.

Standard office furniture locks use low-security wafer cylinders or small tubular cylinders that cannot be masterkeyed into a building's door hardware key system. A facility manager who keys their entry doors to a master system still needs a separate key for every cabinet, which creates key management complexity and the inevitable problem of employees losing multiple keys.

The CL Series solves this by using a standard Schlage cylinder that can be masterkeyed, grand masterkeyed, and keyed alike using the same key system as the building's ND Series cylindrical locks, L Series mortise locks, and B Series deadbolts. One key operates the offices, the storeroom, and the filing cabinets. This is the core specification reason the CL Series is used in commercial and institutional environments rather than standard hardware store cam locks.

Schlage CL Series Cabinet Lock Parts: Complete Reference

CL10-301: Cylinder Retaining Screw

The CL10-301 is the set screw that holds the cylinder in the cabinet lock housing. It seats into a detent in the cylinder housing and prevents the cylinder from rotating when the key is turned. When this screw loosens or strips, the entire housing rotates with the key instead of only the cylinder plug rotating. The symptom is a lock where turning the key spins the visible cylinder body rather than producing a bolt movement.

The CL10-301 is the most frequently replaced CL Series part. In high-cycle applications where the lock is opened and locked multiple times daily, the retaining screw vibrates loose over months of use. If a CL Series lock begins to feel loose or the cylinder has visible rotational play when the key is not inserted, check the CL10-301 first before diagnosing the cylinder or bolt mechanism. Tightening or replacing the CL10-301 resolves most CL Series cylinder rotation complaints without any additional parts.

CL10-350: Adapter Spacer

The CL10-350 is a spacer that accommodates thicker cabinet door or drawer face materials. When the cabinet panel is thicker than the standard lock body projection, the spacer extends the lock assembly to the correct mounting depth. Without the correct spacer, the cylinder head may sit below the cabinet face surface, preventing the key from engaging correctly or leaving the retaining screw inaccessible. The CL10-350 is also used when a standard-length CL Series cylinder does not reach the correct bolt engagement depth on a specific cabinet configuration.

CL10-352: Slotted Strike

The CL10-352 is a slotted strike for CL Series cabinet locks. Unlike a fixed-pocket strike, the slotted design allows the bolt to engage anywhere along the slot length rather than at a single fixed point. This accommodates minor misalignment between the bolt position and the frame pocket without requiring strike relocation or additional adjustments. It is the most forgiving strike option for field installations where the cabinet construction tolerance varies.

The slotted strike is the correct first choice for any CL Series installation where the bolt position relative to the frame has not been precisely measured and confirmed. If the bolt position is known and consistent, a bar strike provides a more secure engagement because it has defined pocket walls that prevent the bolt from shifting laterally under load.

CL10-354 and CL10-355: Bar Strikes

The bar strikes are flat bar-shaped strikes with a bolt pocket for the CL Series deadbolt. Both are 3/4 inch wide and 1-31/32 inch long. The CL10-354 is 1/4 inch thick. The CL10-355 is 1/2 inch thick.

The thickness distinction matters for how deep the bolt must travel before engaging the strike. A 1/4 inch bar strike is flush or nearly flush with the cabinet frame face, meaning the bolt engages quickly and with minimal throw distance consumed by the strike material itself. A 1/2 inch bar strike positions the bolt pocket deeper into the frame, requiring more bolt travel to engage. This is used when the gap between the cabinet door and frame requires additional standoff to position the pocket at the correct engagement depth.

Schlage 36-031: Trim Collar

The Schlage 36-031 trim collar is a cosmetic component that installs around the cylinder face to cover the bore hole in the cabinet panel. When a cabinet panel bore is oversized or the previous lock left a visible gap around the cylinder, the trim collar provides a finished appearance. It also covers minor damage around the bore from forced entry or tool marks. The 36-031 is available in standard finishes to match the cylinder face.

CL Series Lock Configurations: Door vs Drawer

The CL Series offers different cam configurations for door and drawer applications. A door lock uses a deadbolt cam that extends perpendicular to the cylinder body when the key is turned. A drawer lock uses a cam that rotates to release a drawer slide mechanism. The bolt style and cam orientation are specified at the full lock assembly level, not at the individual parts level covered here. When ordering replacement parts, always confirm whether the installation is a door or drawer configuration before ordering any cam or bolt component, as they are not interchangeable between the two applications.

Schlage HL6 Series Hospital Latch Lock: What It Is and Why It Exists

The Schlage HL6 Series hospital latch is a push-pull latch lock designed specifically for healthcare environments. The name comes from its defining feature: a paddle rather than a lever or knob. Instead of gripping and turning hardware, a person pushes or pulls the paddle to retract the latch. The paddle's short throw angle means the latch retracts with a light push or pull force that does not require tight grasping, tight pinching, or twisting of the wrist.

This is not just an ergonomic convenience. It serves three distinct functions in healthcare settings that no standard cylindrical or mortise lever lock satisfies.

First, it enables hands-free door operation. Nurses and doctors carrying equipment, trays, or patients cannot easily grip a lever. A paddle retracted with a forearm or elbow keeps the hands free and the door operational. Second, it delivers quiet operation. The HL Series is specifically engineered to reduce latch engagement and mechanism noise, which is a material factor in patient sleep quality and recovery in room-by-room studies. The current HL6 generation is 50% quieter than the previous HL Series design. Third, it provides institution-specific security functions including anti-barricade key override for behavioral health applications.

The HL6 uses the Schlage L Series mortise lock chassis: the same Grade 1 commercial mortise mechanism used in high-security L Series mortise locks on main building entries. This gives the HL6 the durability required for healthcare environments where doors cycle thousands of times per year under high-traffic, round-the-clock use.

HL6 Series Parts: What SecurityParts.com Stocks

HL6 Mortise vs Tubular: Choosing the Right Configuration

The HL6 is available in mortise and tubular versions. The mortise version uses the Schlage L Series mortise lock case installed inside the door, which requires a routed mortise pocket in the door edge. The tubular version uses a standard tubular latch mechanism, which requires only a face bore and edge bore without a mortise pocket.

For new construction healthcare facilities, mortise is almost always the correct specification. The L Series mortise chassis provides Grade 1 strength and durability that matches the high cycle count demands of a hospital patient room door. It is also compatible with the Von Duprin 9875 and 9975 mortise exit devices, which may be required on specific door applications within the healthcare building.

The tubular version is appropriate for renovation projects where the existing doors do not have a mortise prep and the budget does not allow door replacement. A tubular HL6 on an existing tubular prep door provides the push-pull ergonomics and quiet operation of the HL6 without requiring door replacement. The tradeoff is that the tubular version does not achieve the same durability under maximum cycle load as the mortise version.

HL6 Functions: Healthcare-Specific Security Operations

The HL6 offers 14 mechanical mortise functions, 2 electrified mortise functions, and 3 tubular functions. The functions that matter most for healthcare parts ordering are the ones with specific clinical safety features.

HL6-9010: Passage Function

The latchbolt is retracted by the paddle from either side. Inside paddle always free for immediate egress. The most basic function, used on non-secured interior corridor doors where free passage is always required. Parts for a passage function HL6 are the paddle assembly (mortise or tubular, engraved or non-engraved) and the cover assembly.

HL6-9040: Privacy Function (Bath/Bedroom)

The latchbolt is retracted by the paddle from either side unless the outside paddle is locked by the inside thumbturn. Actuating the inside paddle or closing the door unlocks the outside paddle. For emergency access, the outside has a release mechanism. This is the standard patient bathroom and private room function where a patient needs inside privacy but staff need emergency outside access.

HL6-9060: Apartment Entrance Function

The latchbolt is retracted from either side unless the outside is locked by key from inside. When locked, key or inside paddle retracts the latchbolt. Used on patient rooms where both patient privacy and staff key access are required simultaneously.

HL6-9070: Classroom Function

Latchbolt retracted by paddle from either side unless outside paddle is locked by key. Inside paddle always free for immediate egress. For medication rooms, treatment rooms, and other controlled-access clinical spaces where staff lock access from outside but egress from inside is always free.

HL6-9080: Storeroom Function

Latchbolt retracted by inside paddle or outside key. Outside paddle always inoperative. Auxiliary latch deadlocks latchbolt when door is closed. Inside paddle always free for immediate egress. For medical supply rooms and pharmacy areas where entry is controlled exclusively by key.

HL6-9082: Institution Function (Anti-Barricade)

Latchbolt retracted by key from either side. Outside paddle always inoperative. Inside paddle always free for immediate egress. The key override feature on this function allows the outside key to retract the latch even if the inside is being manually held. This is the anti-barricade function critical for behavioral health, psychiatric, and patient room applications where preventing barricade situations is a clinical safety requirement.

HL6 Special Options That Affect Parts Ordering

Lead Lining for Radiation Rooms

The HL6 lock case is available with a 1/8 inch lead lining insert for X-ray rooms, radiation therapy rooms, and any space where the door hardware must contribute to the room's radiation shielding. The lead lining is a factory option, not a field modification. It cannot be added to an existing non-lead-lined lock case.

When a radiation room HL6 needs paddle assembly replacement, the replacement paddle does not include the lead lining. The lead lining is inside the lock case body, not in the paddle. A paddle replacement on a lead-lined HL6 does not require a lead-lined paddle. The case body retains its lead lining throughout the product's life unless the entire lock case is replaced.

If the entire lock case of a lead-lined HL6 must be replaced (due to forced entry damage or mechanism failure), the replacement must be specified with the lead lining option. Ordering a standard non-lined replacement case for a radiation room removes the radiation protection at that opening without any visible indicator that a change has occurred.

Quiet Operation Engineering

The HL Series achieved its documented 50% noise reduction improvement over the previous HL Series generation through redesigned internal mechanism geometry that reduces the impact force of the latch bolt engaging the strike. This is not an adjustable feature and requires no specific maintenance to maintain. However, a correctly aligned strike is necessary for the quiet engagement to function as designed. A misaligned strike that causes the latch to contact the strike face edge rather than enter the bolt pocket cleanly produces noise regardless of the mechanism design. When a previously quiet HL6 installation begins producing latch noise, strike alignment is the first item to check before assuming the mechanism has failed.

Von Duprin Compatibility

The HL6 mortise version is compatible with the Von Duprin 9875 and 9975 mortise exit devices. This allows a single door to be specified with the HL6 push-pull operation on the inside and Von Duprin panic exit hardware on the outside, which is the standard configuration for healthcare patient room doors on required egress paths where both push-pull access and panic hardware are needed simultaneously. This compatibility is not available on the tubular version. Browse commercial exit device parts at SecurityParts.com for Von Duprin mortise exit device components.

Mounting Orientations: What Competitors Never Explain

The HL6 paddle assembly mounts in four orientations that determine how the paddles are positioned relative to the latch: handles up, handles down, one handle up with the other down, or horizontal with handles pointing away from the latch. This flexibility is what allows the HL6 to serve multiple door configurations without a different product for each application.

For corridor patient room doors, handles-down is the most common mounting: the paddles hang below the latch body in the familiar push-pull position that most healthcare workers recognize instinctively. For non-keyed passage functions, handles-up mounting is available, positioning the paddles above the latch body. Horizontal mounting is used when the door configuration requires the paddles to point horizontally rather than vertically.

How to Order the Correct Part for Each Product Line

CL Series Cabinet Lock Parts

Three pieces of information are needed: the symptom (cylinder rotates, bolt does not engage, bore is oversized), the application (door or drawer), and the cabinet panel gap dimension (for bar strike thickness selection). The CL10-301 retaining screw resolves most cylinder rotation complaints. The CL10-352 slotted strike is the safest first choice for any new strike installation. Bar strike thickness (CL10-354 vs CL10-355) is determined by measuring the gap between the closed door face and the cabinet frame face.

HL6 Hospital Latch Parts

Four pieces of information are needed: mortise or tubular chassis (confirmed by whether the door has a routed mortise pocket or only bore holes), engraved or non-engraved paddle, function (passage, privacy, classroom, storeroom, or institution), and whether the lock case has lead lining. Cylinders and housings are always ordered separately. For bent tab strike vs standard ASA strike, confirm the frame prep before ordering.
