Description
CompX National Disc Tumbler Cam Lock For Cabinets
CompX National disc tumbler cam lock, 1-7/16 inch cylinder with 90 degree CW rotation, 3/4 inch mounting hole C8055-C390A-4G secures drawers and cabinet doors using a disc tumbler mechanism, giving installers a defined keying system for furniture and casework jobs. The 1-7/16 inch cylinder length provides reach through typical front and frame thicknesses within that dimension so the lock body seats firmly and supports smooth cam action. A 3/4 inch mounting hole requirement matches common cabinet boring sizes, which simplifies layout when adding security to new or existing units. The 90 degree clockwise rotation works with the supplied stop washer so the cam turns a controlled quarter-turn, helping align the locked and unlocked positions predictably. Key removable in both locked and unlocked positions lets users remove the key after turning either way, which supports flexible access control in shared or shop environments.
Key Functional Details For Daily Lock Use
- The antique brass cam lock finish identified in the description presents an antique brass appearance that coordinates with traditional cabinet hardware, so security hardware can visually match other exposed components on doors and drawers.
- The stop washer supplied with each lock limits cam travel to 90 degrees, giving a consistent quarter-turn motion that helps installers align strike points and users quickly feel when the lock is fully engaged or released.
- Cams provided for lipped or overlay construction use a straight cam with 1-1/2 inch extension, allowing the cam to reach behind an overlay front and frame so the lock can engage the cabinet structure on overlay-style installations.
- Cams for flush construction use a formed cam with 1-1/8 inch extension and 11/32 inch offset, positioning the cam properly behind a flush front so the locking point sits in the correct plane for face-frame or flush-panel cabinets.
- Key removable in both locked and unlocked positions means the key can be withdrawn in either state, which lets users leave doors unlocked without a key hanging and allows quick relocking without a dedicated key position search.
- Stock keying options KA, KD, and KDMKD give shops choices for all keyed alike, all keyed different, or keyed different master keyed systems, supporting project-level control over how many locks share keys or respond to a master key.
Cam Lock Mounting And Cylinder Fit Details
The 3/4 inch mounting hole specification means the cabinet or drawer front uses a 3/4 inch bored hole, so boring patterns can match standard jigs when preparing wood or panel fronts. The note that the combined thickness of front and frame cannot exceed the cylinder length means the 1-7/16 inch cylinder must pass fully through both layers to seat the mounting nut and washers, guiding material selection and construction style. For overlay applications using a 3/4 inch front and 3/4 inch frame, the data specifies using the NLC8053 lock with the NLC7014-2C cam, which indicates this particular C8055-C390A-4G model suits overlay conditions where total front and frame thickness stay within the listed cylinder length.
Where This Antique Brass Cam Lock Fits Best
Applications On Drawers And Cabinet Doors
The web description states this cam lock is for drawers and right-hand or left-hand doors, so it handles common cabinet storage points in kitchens, offices, or shop furniture where swing direction varies. Support for both right-hand and left-hand doors means the same lock model installs on either hinge orientation, allowing one part number across mirrored layouts. Cams for lipped or overlay construction, using the straight cam with 1-1/2 inch extension, serve doors and drawers where the front overlays the frame, letting the cam reach past the lip. For flush construction, the formed cam with 1-1/8 inch extension and 11/32 inch offset aligns the lock action behind a flush front so the cam catches the case or frame plane without extra spacers. The antique brass finish described as CAM LOCK, ANTIQUE BRASS makes this lock suited to cabinets where visible hardware needs a warm, traditional tone that blends with classic pulls and hinges.
Details That Support Repeatable Lock Installations
The disc tumbler cam lock design from CompX National provides a defined locking mechanism that works with the supplied stop washer to achieve 90 degree clockwise rotation, giving installers a reliable template for orienting cams and strikes. A 3/4 inch mounting hole spec pairs with the cylinder body so the lock fits snugly in a standard bore, helping maintain alignment between the cam and strike over repeated use. The requirement that front and frame thickness stay within the cylinder length clarifies how far the lock can project, which helps fabricators choose door and frame build-ups that allow the mounting nut and washers to clamp securely. The key removable in both locked and unlocked positions influences workflow by letting staff lock or unlock, remove the key, and move on without returning the plug to a neutral position. Stock keying options KA, KD, and KDMKD organize how multiple locks interact: KA sets can operate from the same key number for banks of cabinets, KD sets assign different key numbers where separation is needed, and KDMKD systems maintain individual keys while still responding to a master key, which streamlines controlled access patterns.
