CompX Disc Tumbler Deadbolt Lock For Doors

CompX National disc tumbler deadbolt lock provides key-operated security for drawers and doors where a compact deadbolt is needed. This lock uses a 15/16 inch cylinder length, so it suits cabinet constructions designed around that body depth.

The lock is surface mounted, so it fastens directly to the drawer or door face, supporting straightforward placement on cabinet jobs. Keying is C346A keyed alike, which allows multiple locks ordered with this code to be operated by the same key across a run of cabinetry. The bright nickel finish on the lock presents a clean metallic appearance that coordinates with many commonly used decorative hardware finishes on cabinets and casework.

Deadbolt Lock Details That Support Cabinet Work

• The 15/16 inch cylinder length sets a defined body depth, which helps layout on typical cabinet door and drawer thicknesses without overextending into the interior space.
• The required 7/8 inch diameter mounting hole gives a precise drilling dimension, so installers can repeat hole locations accurately across multiple fronts during a project.
• The surface mounted application allows the lock body to sit on the door or drawer surface, which simplifies positioning and reduces prep compared with concealed lock styles.
• The bright nickel finish offers a metallic look that coordinates with many nickel and chrome cabinet pulls, maintaining a consistent appearance on visible faces.
• The disc tumbler construction works with the specified key system, supporting keyed security on cabinetry where a deadbolt-style lock is preferred.
