CompX National Disc Tumbler Cam Lock, 1-7/16" Cylinder with 90 Degree CW Rotation, 3/4" Mounting Hole C8055-C642A-14A

CompX National Disc Tumbler Cam Lock For Cabinets

CompX National disc tumbler cam lock is a cam lock with a 1-7/16 inch cylinder that secures cabinet doors or drawers where a cylinder of that length fits the construction, giving installers a defined reach through the front and frame. The lock uses a 3/4 inch mounting hole, so case boring follows a clear dimension for repeatable layout across multiple fronts. The bright nickel finish identifies this specific CAM LOCK, BRIGHT NICKEL version C8055-C642A-14A, helping teams match visual appearance on jobs that already use this finish. The lock has 90 degree clockwise rotation, so the cam swing is predictable and easy to coordinate with strike location and stop washer position. Each lock comes with one stop washer that allows the cam to turn 90 degrees, so rotation is constrained to a usable quarter-turn for typical cabinet applications.

Cam Lock Details That Support Cabinet Work

• The 1-7/16 inch cylinder length provides reach through the front and frame within that dimension, which matters when matching lock depth to overlay or flush cabinet construction.
• The 3/4 inch mounting hole specification defines the bore size in the panel, which lets fabricators set up boring equipment or templates around a single, repeatable hole diameter.
• 90 degree clockwise rotation controls the cam swing to a quarter turn, which helps position the cam relative to strikes and avoids over-rotation that can interfere with adjoining parts.
• The stop washer that allows 90 degree cam turn sets a mechanical limit, which supports consistent locked and unlocked positions across doors and drawers using the same lock.
• Stock keying options KA, KD, and KDMKD define whether locks are all keyed alike, all keyed different, or master keyed, which matters for planning user access and master key control.

Mounting And Construction Options For This Cam Lock

This CompX National cam lock fits a 3/4 inch mounting hole, so installers drill or punch that diameter in the cabinet front to seat the 1-7/16 inch cylinder. Cams are provided for lipped or overlay constructions using a straight cam with 1-1/2 inch extension, which lets the cam reach behind an overlaid front. For flush constructions, a formed cam with 1-1/8 inch extension and 11/32 inch offset positions the locking surface relative to the front. For overlay applications, the combined thickness of front and frame cannot exceed the cylinder length listed, so front plus frame must fall within that depth for correct operation.

How This Bright Nickel Cam Lock Works In Use

Using The Cam Lock On Drawers And Doors

This CAM LOCK, BRIGHT NICKEL is specified for drawers and for right-hand or left-hand doors, so one lock style can be applied across common cabinet layouts. The key is removable in both locked and unlocked positions, which allows users to remove the key after locking or leave the lock open without leaving a key hanging, shaping how access is managed on site. The straight cam with 1-1/2 inch extension for lipped or overlay construction reaches behind door or drawer fronts that overlap the case, tying the lock body on the front to a strike or frame behind. The formed cam with 1-1/8 inch extension and 11/32 inch offset for flush construction aligns the cam with the case or strike surface on installations where the front is even with the cabinet sides. This flexibility in cam style lets the same lock body serve different cabinet constructions while maintaining consistent function.

Details That Affect Fit, Keying, And Workflow

The 90 degree clockwise rotation, controlled by the stop washer, defines exactly how far the cam travels, so hardware layouts can be repeated from cabinet to cabinet without rethinking cam swing. Supplied cams for lipped/overlay and flush constructions give two extension choices, which helps match reach to door or drawer geometry and reduces rework from misaligned strikes. Stock keying options are listed as KA, KD, and KDMKD, where KA means all keyed alike to the specified key number with no master key function, KD means all keyed different with various lock numbers and no master key function, and KDMKD means all keyed different and master keyed so a master key will operate those locks. These keying structures allow planners to decide whether groups of locks operate from a common key or from individual keys with or without master key capability.
