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

CompX National Disc Tumbler Deadbolt Lock Details

CompX National disc tumbler deadbolt lock provides a keyed locking point for drawers and doors, so a single lock secures the panel at the cylinder location. The 15/16 inch cylinder length positions the locking mechanism through standard cabinet material, helping the bolt reach the strike area on typical drawer and door constructions. The lock requires a 7/8 inch diameter mounting hole, giving installers a clear drill size for accurate placement in wood or similar substrates. This model is surface mounted, so the body mounts on the interior surface of the drawer or door face where it can engage the frame. The bright nickel finish presents a clean, metallic appearance at the exposed cylinder, which suits many cabinet and casework styles. The disc tumbler design works with the specified key blank, tying security performance directly to a known keying system.

Deadbolt Lock Features That Support Cabinet Work

• The 15/16 inch cylinder length allows the deadbolt lock to extend through drawer or door fronts, so the locking action reaches the interior where it can secure the cabinet body.
• The 7/8 inch diameter mounting hole requirement defines the drill size for the cylinder, helping installers locate and bore a clean, properly sized opening in one pass.
• The surface mounted design places the disc tumbler deadbolt lock body on the inside face, simplifying layout because the lock mounts directly on the interior surface of drawers and doors.
• The bright nickel finish on the cylinder creates a consistent metallic look at the front, matching other bright nickel hardware on cabinets and furniture projects.
• The C415A keyed alike keying allows multiple locks with this code to operate on the same key, so users can manage groups of drawers and doors with a single key pattern.
• The ability to key together with other disc tumbler locks using the D8785 key blank lets a project share one key profile across different lock locations in the same installation.

Mounting And Key Operation For This Lock

This disc tumbler deadbolt door lock is surface mounted for drawers and doors, placing the housing on the interior surface while the 15/16 inch cylinder passes through the 7/8 inch diameter hole. That layout lets the cylinder sit flush at the front while the locking components stay protected inside the cabinet. The lock uses a key removable in both locked and unlocked positions, so the key can be taken out after operating the lock in either state. That behavior allows the operator to leave the cylinder without a key showing whether the drawer or door is currently secured or open. The keyed alike C415A configuration defines the key code, providing consistent operation when multiple locks are ordered under the same code.

Using This Deadbolt Lock In Cabinet Projects

Where This CompX Deadbolt Lock Is Applied

This CompX National disc tumbler deadbolt door lock is specified for drawers and doors, so it serves on casework where a rotating cylinder deadbolt is needed at the panel edge. Its surface mounted construction positions the lock body on the inside face of the drawer or door, which suits cabinet interiors that have enough flat area for mounting. The 15/16 inch cylinder length paired with the 7/8 inch mounting hole requirement aligns with many common drawer front and door thicknesses, placing the cylinder trim at the exterior and the bolt mechanism behind the panel. In a run of cabinets or fixtures, the bright nickel finish presents a uniform appearance wherever the cylinder is visible on fronts or stiles.

Why Keying And Hole Size Matter For Workflow

The keyed alike C415A configuration means this deadbolt lock can operate with the same key as other locks using that code, which streamlines day-to-day use when multiple drawers and doors must be accessed regularly. Because it will key together with all other disc tumbler locks using the D8785 key blank, a project can share one key pattern for different lock positions, reducing time spent carrying and sorting separate keys. The requirement for a 7/8 inch diameter mounting hole standardizes drilling operations, so installers can use a single bit size for all cylinder locations on a job. Key removable in both locked and unlocked positions lets users remove the key after turning to either state, which supports workflows where supervisors lock storage at closing and then remove keys from every cylinder.
