CompX National Disc Tumbler Cam Lock, 1-7/16" Cylinder with 90 Degree CW Rotation, 3/4" Mounting Hole C8055-C346A-3
Description
CompX National Disc Tumbler Cam Lock For Casework
CompX National disc tumbler cam lock, 1-7/16 inch cylinder with 90 degree CW rotation, 3/4 inch mounting hole C8055-C346A-3 is a lock designed for casework using a standard 3/4 inch bore. The 1-7/16 inch cylinder length supports applications where the front and frame thickness must stay within that dimension, which helps match the lock to typical cabinet construction. The 90 degree clockwise rotation works with the provided stop washer, so the cam turns through a controlled quarter-turn, which gives predictable locked and unlocked positions. This product is a cam lock, so it secures by rotating a cam behind the panel, which suits drawers and cabinet doors. The bright brass description identifies the finish appearance, which supports projects where a brass look is desired across visible hardware.
Cam Lock Details That Support Real Installations
- The stop washer allows the cam to turn 90 degrees, which gives a defined throw for aligning the cam with strikes or cabinet edges.
- The lock is specified for drawers, right-hand doors, or left-hand doors, so one part number can be used across multiple cabinet orientations.
- Cams are provided for lipped or overlay construction using a straight cam with 1-1/2 inch extension, which lets the cam reach around a lip or overlay front.
- Cams are also provided for flush construction using a formed cam with 1-1/8 inch extension and 11/32 inch offset, which positions the cam to engage behind a flush front.
- For overlay applications, the combined thickness of front and frame cannot exceed the cylinder length, so the lock body can fully clamp through the material stack.
Installation Fit And Cylinder Length Considerations
The 3/4 inch mounting hole specification means the cam lock is sized for a 3/4 inch diameter bore through the cabinet front, which matches common drilling patterns. The cylinder length requirement for overlay applications limits the sum of front and frame thickness to the listed cylinder dimension, which avoids leaving threads too short to seat the mounting nut. A straight cam with 1-1/2 inch extension supports reaching further behind doors or drawer fronts, while the formed cam with 1-1/8 inch extension and 11/32 inch offset positions the locking surface closer, which helps when working with flush-front cabinets.
Using This Bright Brass Cam Lock In Projects
Applications Across Drawers And Cabinet Doors
This bright brass cam lock is described for drawers, right-hand doors, and left-hand doors, so it fits various cabinet layouts in the same job. The disc tumbler cam lock design suits furniture, casework, or other cabinetry where a rotating cam needs to capture behind a frame or strike. For lipped or overlay construction, the straight cam with 1-1/2 inch extension reaches past the lip, so the cam can rotate behind the cabinet frame to hold the front closed. For flush construction, the formed cam with 1-1/8 inch extension and 11/32 inch offset keeps the cam closer to the door back, which helps engage behind a flush panel without over-travel.
Keying Options And Rotation For Repeatable Results
This lock uses 90 degree clockwise rotation with the supplied stop washer, which sets a consistent quarter-turn between locked and unlocked positions and simplifies aligning key position with the front. Key removable in both locked and unlocked positions allows the cylinder to release the key after turning either way, which can support workflows where the operator removes the key after opening or after securing the cabinet. Stock keying options are specified as KA, KD, and KDMKD, describing groups keyed alike, keyed different, or keyed different and master keyed, which lets projects match locks to a chosen key control scheme. The manufacturer part number C8055-C346A-3 identifies this specific bright brass disc tumbler cam lock configuration, which helps keep replacements and additional units consistent with existing installations.
