CompX National Disc Tumbler Cam Lock For Cabinets

CompX National disc tumbler cam lock gives drawers and cabinet doors a keyed locking point using a 1-3/16 inch cylinder, so you can match hardware to common casework thicknesses. The lock uses 90 degree clockwise rotation with a stop washer, which limits cam travel to a quarter-turn for quick lock and unlock in routine use. Flat black finish ties into dark casework and fixtures where a low-visibility lock face is preferred on the job. The cam lock is keyed in groups per the C8053-MKKD-Y21 designation, so keyed control can be planned across related installations. Key removable in both locked and unlocked positions allows keys to be pulled after cycling, which can help during shop fitting or service work. The disc tumbler design provides a compact lock body that fits typical cam lock cutouts in furniture and cabinetry.

Lock Details That Support Cabinet Workflows

• Stop washer limiting the cam to 90 degree turn provides a defined open and closed position, which simplifies handle orientation and user operation.
• Usable on drawers plus right-hand or left-hand doors, so one lock type can be applied across multiple cabinet configurations in a project.
• Cams for lipped or overlay and flush construction give options to reach the strike whether the door overlays the face or sits flush in the frame.
• Straight cam with 1-1/2 inch extension serves overlay construction, helping the cam reach behind a projecting front and engage the case.
• Formed cam with 1-1/8 inch extension and 11/32 inch offset serves flush construction, stepping the cam in to align with the frame or strike.
• Key removable in locked and unlocked positions lets installers cycle locks during layout or rekeying without leaving keys hanging in the cylinder.

Practical Mounting And Overlay Fit Considerations

The 1-3/16 inch cylinder length sets the maximum combined thickness of front and frame in overlay applications, so matching this dimension keeps the cam in working range. For overlay work using a 3/4 inch front and 3/4 inch frame, the manufacturer specifies pairing an NLC8053 lock with an NLC7014-2C cam, which signals that this assembly is tuned for that thicker build-up. Supplied cams cover typical lipped or overlay and flush layouts, so casework with moderate face thickness and standard clearances can be addressed without redesigning the lock location. The stop washer used with the 90 degree clockwise rotation helps the cam stop consistently against the case edge or strike, which supports repeatable alignment from cabinet to cabinet when you follow a common boring layout.

How This C8053-MKKD-Y21 Cam Lock Works In Use

Where This Flat Black Cam Lock Is Applied

This C8053-MKKD-Y21 cam lock is specified for drawers and for right-hand or left-hand doors, so it fits a wide range of furniture, cabinet, and fixture layouts using the same core hardware. The ability to cover lipped or overlay construction with the straight cam and flush construction with the formed cam means the lock can be used on face-frame cabinets and on frameless or inset doors within the dimensional limits of the 1-3/16 inch cylinder. In overlay situations, the combined thickness of front and frame needs to stay within that cylinder length so the threaded body can clamp the material and still position the cam where it can clear and rotate. When an overlay assembly uses both a 3/4 inch front and a 3/4 inch frame, the noted NLC8053 lock and NLC7014-2C cam combination indicates a dedicated pairing for that heavier build, which can guide selection for thicker fronts.

Keying Options And Rotation That Reduce Rework

The stock keying descriptions tied to this series define how locks relate to each other in the field: KA provides all locks keyed alike to a specified key number, where a master key will not operate them, useful when every opening in a run needs the same key. KD provides all locks keyed different with various lock numbers, again without master key function, which helps separate access between locations or users. KDMKD provides all locks keyed different but master keyed, so individual keys work their own locks while a master key works across the group for supervised access. The C8053-MKKD-Y21 part number identifies a version keyed in groups within that system, which supports planned key organization across a project. Combining these keying structures with the 90 degree clockwise rotation and key removable in both locked and unlocked positions creates a lock that can be cycled, keyed, and operated in predictable ways during installation and later service.
