CompX National Disc Tumbler Deadbolt Lock, 15/16" Cylinder with 7/8" Mounting Hole, C415A Keyed Alike, Antique Brass

CompX National Disc Tumbler Deadbolt Lock Details

CompX National disc tumbler deadbolt lock secures cabinet drawers and doors using a deadbolt mechanism that works in woodworking and similar applications where keyed control is needed. The lock uses a 15/16 inch cylinder length, which positions the plug correctly through typical cabinet material so the key engages smoothly during daily use. It requires a 7/8 inch diameter mounting hole, so installers can drill a consistent bore and expect a snug fit that helps keep the cylinder stable. The lock is surface mounted, allowing it to be added to existing drawers and doors in shops or built-ins without altering case construction. An antique brass finish gives the lock a specific visual match to antique brass hardware lines, which helps maintain a uniform appearance across doors, drawers, and surrounding fittings.

Key Deadbolt Lock Features For Cabinet Work

• The 15/16 inch cylinder length sets the locking mechanism at a depth suited to many cabinet door and drawer thicknesses, which helps the key turn cleanly without binding during opening and closing.
• The required 7/8 inch diameter mounting hole defines the exact bore size, which streamlines drilling layouts and reduces rework when repeating the same lock across a run of cabinets.
• Surface mounted design positions the deadbolt on the cabinet face, which supports retrofit work on existing drawers and doors where mortising or deep case modification is not desired.
• Antique brass finish coordinates with antique brass hardware programs, helping installers keep visible hardware consistent on doors and drawers in finished rooms.
• C415A keyed alike option allows locks with that code to use the same key, simplifying key management for banks of drawers or doors that share access requirements.

Mounting And Cylinder Fit For This Deadbolt Lock

This CompX National deadbolt lock is surface mounted on doors or drawers, so it fastens to the exterior face while the cylinder passes through a prepared opening. The 7/8 inch diameter mounting hole requirement sets the drill bit size, which supports accurate hole placement and repeatable installs across multiple cabinets. With a 15/16 inch cylinder length, the lock body projects through the panel to reach the front, so the key engages the tumbler stack consistently on cabinet thicknesses suited to that length. The disc tumbler construction provides the locking function within this cylinder, which keeps the operation concentrated at the drilled opening for straightforward alignment.

Using This Deadbolt Lock On Drawers And Doors

Where This Deadbolt Lock Fits In Cabinet Projects

This CompX National disc tumbler deadbolt lock is described for drawers and doors, so it applies to both sliding drawer fronts and hinged cabinet doors in woodworking installations. Because it is surface mounted, the lock works on cabinet faces where the installer can access the interior to receive the deadbolt, which is common in casework and built-in storage. The antique brass finish aligns it with antique brass cabinet hardware programs, so it can be used on visible doors and drawers in kitchens, offices, or furniture-style pieces that rely on that finish group. The 7/8 inch mounting hole requirement also means it fits layouts where that bore size can be drilled cleanly through the face panel. The disc tumbler mechanism uses the key to drive a deadbolt action suitable for restricting access to drawers and doors in these settings.

Why Cylinder Length, Keying, And Operation Matter

The 15/16 inch cylinder length defines how far the lock projects through the cabinet material, which affects how the key seats and turns in everyday use. A cylinder sized for this depth helps maintain smooth rotation when locking and unlocking drawers or doors that match that thickness range. The key is removable in both locked and unlocked positions, so users can withdraw the key after securing the cabinet or leave it out while the cabinet remains open but keyed for later locking. The lock is keyed alike to C415A code, which means multiple locks with that code operate from the same key, reducing key counts in installations where many drawers or doors must be controlled together. It will key together with all other disc tumbler locks using the D8785 key blank, allowing a disc tumbler system based on that blank to operate this lock alongside other matching locks in the same environment.
