Timberline Type 251 double door lock is a surface mounted cylinder body designed to secure two adjacent doors using a single lock point, so one lock controls both doors instead of adding separate units. This CompX Timberline lock body is specified as Type 251 and CB-251, tying it directly to Timberline systems where matching part numbers keep projects consistent across multiple cabinets. The lock uses a 3/4 inch cam length with an 11/16 inch offset, creating the reach and step needed to catch the paired strike plates on side-by-side doors. The cylinder body functions as a double door lock without a spring catch, which means the cam itself holds the doors closed when locked for a simple, positive engagement. As a deadbolt-style lock in the Locks and Latches Deadbolt Locks category, it provides a direct turn-to-lock action that suits straightforward cabinet security layouts.
The Timberline Type 251 cam body is described as working with either overlay or inset doors, so the same lock body can be applied across different face configurations in a project. This flexibility matters when a shop mixes overlay and inset cabinets but wants a common locking solution. The required 16.5 mm diameter bore hole defines the drilling operation for receiving the cylinder body, giving a precise hole size that keeps the lock centered and supported in the door. A turn key counter-clockwise to lock operation means the direction of key rotation is fixed, which helps users operate multiple locks consistently. The key removable in both locked and unlocked positions feature allows the key to be withdrawn after setting the lock either way, which supports workflows where keys are stored separately after locking or where keyed access is only needed briefly.
The CB-251 cylinder body is specifically described as a Timberline Type 251 double door lock with 11/16 inch offset, so it is intended for cabinets where two adjacent doors need to lock together. The surface mounted design places the lock on the door surface, allowing installers to handle positioning from the outside face of the doors. Because the lock works with either overlay or inset doors, the same CB-251 part can be specified across different cabinet styles while maintaining a consistent Timberline lock family. The 3/4 inch cam length provides the throw needed to reach the TLSP100 and TLSP257 strike plates that are referenced for this lock. Those strike plates are listed as sold separately, and one of each is required per lock, giving a defined hardware pairing that coordinates the cam reach with the door frame or adjacent door edge. With this setup, the cam engages both strike plates so the lock secures the two doors together when turned.
The cylinder body requires a 16.5 mm diameter bore hole, providing a repeatable drilling measurement that helps jigs and drilling patterns line up across multiple doors in a run. The lock functions without a spring catch, so the mechanical cam action is responsible for holding the doors shut once turned into the strike plates, which creates a clear locked or unlocked state. Turning the key counter-clockwise to lock standardizes the user motion across Timberline Type 251 installations, reducing confusion when several locks share the same operation. The key removable in both locked and unlocked positions characteristic means the user can remove the key after locking or after leaving the doors open, which supports cabinet environments where keys are handled by different personnel. Being categorized as a Deadbolt Lock reinforces that the CB-251 relies on a direct cam throw rather than a latching spring, which suits straightforward security needs on cabinet and furniture applications.
