CompX National Disc Tumbler Rear Mount Cam Lock, 7/8" Cylinder with 3/4" Mounting Hole, Bright Brass C8080-C415A-3

CompX National Disc Tumbler Cam Lock For Cabinets

CompX National disc tumbler cam lock gives doors and drawers a keyed locking point so panels stay secured when closed. The disc tumbler mechanism controls the lock operation, which matters when matching to existing CompX National key systems in a shop or commercial setting. A bright brass finish defines the visual appearance, which helps match other bright brass hardware in the same installation. The rear mount cam lock format places the cam behind the panel, which is useful when the design calls for the lock body to sit through a drilled hole rather than clamp from the front. A 7/8 inch cylinder length works with common cabinet and drawer front thicknesses in woodworking projects. The lock uses a 3/4 inch mounting hole, so installers can drill a consistent diameter across multiple panels for faster layout.

Cam Lock Details That Support Real Cabinet Work

• Two stop washers allow the cam to turn either 90 or 180 degrees, so installers can match the rotation to how the door or drawer needs to latch.
• Stop washers are provided for both 90 and 180 degree cam turns, which helps standardize operation across different cabinet openings using the same lock family.
• The lock is intended for doors and drawers, letting one product style handle typical cabinet fronts and sliding box constructions in woodworking jobs.
• Key removable in both locked and unlocked positions allows keys to be taken out after setting either position, which can help with key management during assembly or service work.
• Two formed cams provide a 1-1/2 inch extension with either 3/32 inch inset or 1/4 inch offset, giving flexibility to engage different strike or frame positions behind the panel.

Rear Mount Cam Lock Fit And Mounting Use

The rear mount cam lock design uses a 7/8 inch cylinder that passes through a 3/4 inch mounting hole, tying the front face to the cam hardware behind the door or drawer front. This relationship between cylinder length and hole size helps the lock seat correctly in typical cabinet thicknesses while letting the cam reach interior framing or strikes. Mounting screws secure the lock and cams, providing a mechanical connection between the rotating cylinder and the cabinet structure. Two stop washers define the end points of rotation, so once selected, the lock repeats the same 90 or 180 degree motion each cycle for predictable feel and alignment with strikes or frames.

How This Bright Brass Cam Lock Works In Use

Cam Lock Applications On Doors And Drawers

This cam lock is specified for doors and drawers, so it fits common cabinet doors that swing on hinges as well as drawer boxes that slide on runners. The 1-1/2 inch extension cams reach behind these fronts, allowing engagement with rails, cabinet sides, or added strike plates depending on the build. Offering two cam geometries - one with 3/32 inch inset and one with 1/4 inch offset - lets installers align the cam travel to existing clearances inside casework. The 7/8 inch cylinder length matches many cabinet faces, giving enough projection for the bright brass face to sit flush while the cam hardware operates behind. Using a rear mount layout, the lock functions from the front of the panel but actually secures by rotating the cam at the back, which suits both new cabinet builds and retrofit lock additions where rear clearance exists.

Keying And Rotation That Reduce Rework

Stock keying options designated as KA mean all locks keyed alike to a specified key number, so multiple cabinets can operate from one key pattern when a master key is not intended. KD keying means all keyed different with various lock numbers, allowing each lock to respond to its own key in applications needing separation. In both cases, the description notes that a master key will not work, which matters in planning access control and avoiding expectations of master key capability. Key removable in both locked and unlocked positions lets installers remove the key after locking or after returning to an open state, useful when many cabinets are being keyed during a project. Additional key changes are available from National Lock via special order, so larger projects can specify different key patterns when required by the layout or security plan.
