CompX National Disc Tumbler Cam Lock, 1-3/16" Cylinder with 90 degree CW Rotation, 3/4" Mounting Hole C8053-C415A-3

CompX National Disc Tumbler Cam Lock For Casework

CompX National disc tumbler cam lock gives drawers and cabinet doors a keyed control point using a 1-3/16 inch cylinder sized for typical casework layouts. The bright brass finish identifies the lock position clearly on the panel, which helps in multi-lock installations. A 3/4 inch mounting hole specification lets installers match this lock to pre-bored or shop-drilled holes without layout guesswork. The 90 degree CW rotation is fixed by design, so the cam only travels through a quarter turn, which helps repeat handle feel and latch engagement from job to job. Key removable in both locked and unlocked positions means the key can be taken away after setting the cam either way, which is useful where users should not leave keys in the lock. Stock keying options KA, KD, and KDMKD support different control schemes on projects that need either shared keys or master keying.

Key Details That Support Everyday Lock Use

• The 1-3/16 inch cylinder length works with fronts and frames where the combined thickness for overlay applications is held under that cylinder dimension, so installers can select panels and frames that allow the cam to operate freely.
• The 3/4 inch mounting hole size ties directly to common drilling operations in drawer and door fronts, helping shops standardize boring patterns across multiple cabinets or fixtures on the same project.
• The 90 degree CW rotation stop washer sets a positive quarter-turn travel, which keeps cam positions consistent for latching and helps minimize over-rotation that could misalign the cam with the strike or frame edge.
• Cams for lipped or overlay construction in a straight 1-1/2 inch extension and for flush construction in a formed 1-1/8 inch extension with 11/32 inch offset give installers options to match different door reveals and construction methods.
• Bright brass construction provides a clear visual reference point on wood or laminate fronts, which is useful when aligning multiple locks on a bank of drawers or doors in commercial and shop environments.

Installation And Mounting Use For This Cam Lock

This cam lock uses a 3/4 inch mounting hole, so it fits cleanly into a standard bored opening during installation. The 1-3/16 inch cylinder length defines how thick the combined front and frame can be in overlay setups, which guides material selection at the design stage. For flush construction, the formed cam with 1-1/8 inch extension and 11/32 inch offset positions the latching point relative to the frame, helping the installer land the cam on the correct strike area. For lipped or overlay work, the straight cam with 1-1/2 inch extension reaches further past the front, which is useful when the frame stands proud of the door or drawer front. The 90 degree CW rotation dictated by the stop washer gives a predictable handle feel and helps align the cam with mating hardware on every cycle.

How This C8053-C415A-3 Cam Lock Works In Practice

Where This Bright Brass Cam Lock Is Applied

This CAM LOCK, BRIGHT BRASS from CompX National is used on drawers and on right-hand or left-hand doors, so it can serve across mixed casework without changing lock families. The cam lock design with disc tumbler mechanism provides keyed control at the panel, which matters on cabinets storing tools, materials, or documents. In overlay applications, the requirement that combined front and frame thickness stay under the 1-3/16 inch cylinder length influences how fabricators build face frames and door overlays. For lipped or overlay construction, the straight cam with 1-1/2 inch extension reaches to engage behind the frame or strike surface. In flush construction, the formed cam with 1-1/8 inch extension and 11/32 inch offset shifts the contact point, helping the cam clear the front edge while still landing firmly on the frame or strike.

Why Rotation, Cams, And Keying Options Matter

The specified 90 degree CW rotation, set up by the stop washer, keeps the cam travel to a quarter turn, which helps avoid interference with nearby hardware and simplifies user operation on busy cabinet runs. Key removable in both locked and unlocked positions affects workflow by allowing installers or supervisors to remove keys after setting the cabinet open or secured, which is useful in shared-shop or commercial locations. Stock keying options KA, KD, and KDMKD define how groups of locks relate to each other: KA lets multiple locks operate on the same key number where a uniform key is desired, KD assigns different lock numbers so each lock stands alone, and KDMKD allows each lock to differ while still accepting a master key. The note that a different lock and cam combination - NLC8053 with NLC7014-2C cam - is required to accommodate an overlay construction using a 3/4 inch front and a 3/4 inch frame highlights how this C8053-C415A-3 model is best suited when the overlay thickness stays within its cylinder length limit, guiding project selection.
