CompX National Disc Tumbler Deadbolt Lock, 1-1/2" Height with 7/16 wide, Bright Nickel, C346A Keyed Alike

CompX Disc Tumbler Deadbolt Lock For Drawers

CompX National disc tumbler deadbolt lock gives a drawer a key-controlled deadbolt that secures the front with a cylinder-operated mechanism, which helps control access to contents in commercial or shop projects. The lock body is built around a 1-1/2 inch height format, so it suits layouts where that vertical dimension fits within the drawer rail or panel design. A 7/16 inch width pairs with the height to define the lock footprint, which matters when routing or boring a precise recess in the drawer or cabinet member. The bright nickel finish provides a clean metal appearance on the cylinder face, which suits applications that call for visible, uniform hardware on casework. C346A keyed alike configuration means multiple locks set to this key number operate with the same key, which simplifies day-to-day use where one key is preferred for several locking drawers.

Keyed Drawer Lock Details That Support Workflow

• The 7/8 inch diameter hole requirement for the cylinder sets the boring size, so installers can drill clean, repeatable holes that correctly seat the cylinder without slop or binding during operation.
• The disc tumbler deadbolt design provides a positive bolt action from the key, so the lock delivers a defined locked and unlocked position that helps avoid partial engagement during daily use.
• The key is required to engage the lock and is removable in both locked and unlocked positions, so users can fully control access while still being able to remove the key after securing or opening the drawer.
• C346A keyed alike stock keying sets all matching locks to the same key number, so multi-drawer or multi-cabinet layouts can be planned around a single key pattern for straightforward access control.
• Other stock keying patterns such as KA, KD, and KDMKD are defined for these locks, so projects can be specified for shared keys, different keys, or master keying to match an access-control scheme.

Lock Cylinder Fit, Keying, And Mounting Use

This drawer lock requires a 7/8 inch diameter hole for the cylinder, which gives installers a clear drilling dimension when setting up boring jigs or drill press stops. The key-controlled operation engages the deadbolt, so the locking action depends directly on turning the key to move the bolt into or out of the strike area. Because the key is removable in both locked and unlocked positions, the user can leave the cylinder without a key hanging, which keeps the front cleaner in service. The bright nickel finish on the exposed parts of the lock presents a metal face that visually matches bright nickel hardware in the same installation.

Applying This Deadbolt Lock In Cabinet Work

Where This Disc Tumbler Drawer Lock Fits Best

This CompX National drawer lock functions as a deadbolt lock for drawers or similar casework members that can accept the 1-1/2 inch height body and 7/16 inch width. The cylinder is sized for a 7/8 inch diameter hole, so fronts or panels must have enough material to support that bore without breaking out. In layouts where several drawers need the same access pattern, the C346A keyed alike arrangement lets multiple locks share one key number, simplifying the hardware plan. When a bright nickel face is desired on visible locking points, the bright nickel finish aligns the lock appearance with other bright nickel hardware on cabinets or furniture.

Why These Keying Options Matter For Daily Use

The defined stock keying options KA, KD, and KDMKD allow a project to be configured around how access is controlled across several locks, which matters when planning shop storage, office casework, or institutional cabinetry. KA provides a keyed alike arrangement to the specified key number where the master key will not work on these locks, so a group of locks can share one operating key without master access. KD sets all locks keyed different with various lock numbers where the master key will not work on these locks, so each lock stands alone in use. KDMKD sets all locks keyed different and master keyed where the master key will work on these locks, so individual keys can operate single locks while a master key still provides overall access. Other key changes are available from National Lock via special order, so projects can be matched to specific key plans when standard patterns are not sufficient.
