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.
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.
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.
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.
The C8053-MKKD-Y21 lock uses a 1-3/16 inch disc tumbler cylinder, which suits typical cabinet and furniture lock boring depths in woodworking applications.
The straight cam has a 1-1/2 inch extension, giving extra reach behind lipped or overlay fronts so the cam can engage the cabinet case or strike surface.
The formed cam has a 1-1/8 inch extension with 11/32 inch offset, which steps the cam inward to meet the frame on flush or inset doors.
The lock rotates 90 degrees clockwise between locked and unlocked with the stop washer, giving a simple quarter-turn motion for users in daily operation.
The cam lock is specified for drawers and for right-hand or left-hand doors, so the same hardware can serve multiple cabinet opening types.
KA locks are all keyed alike without master access, KD locks are all keyed different without master access, and KDMKD locks are all keyed different with a master key that operates them.
This flat black CompX National disc tumbler cam lock brings 1-3/16 inch cylinder sizing, 90 degree clockwise rotation, and cams for both overlay and flush construction together in one part. Those details let drawers and doors across a project share a consistent locking method. The keyed-in-groups C8053-MKKD-Y21 designation and available KA, KD, and KDMKD keying structures support organized key control on multi-opening installations. Select this cam lock when you need coordinated operation, clear cam travel, and matching finish on cabinet and furniture work.
