Timberline Type 256 double door lock is a surface mounted deadbolt lock body designed for locking two adjacent doors, so one cylinder body secures both door leaves in a shared cabinet opening. The Double Door Cylinder Bodies Mounts in 3/4" Material detail means the lock body is suited to installations in common 3/4 inch casework stock, which keeps layout straightforward on typical cabinet builds. The 11/16" offset design positions the locking points correctly relative to the door edges, helping the bolts engage the matching strike plates in a repeatable way. Because the mechanism is a deadbolt style under the CompX Timberline Lock brand, locking both doors happens positively without relying on a spring catch, which matters when doors are used frequently or carry some weight. The CB-256 cylinder body is part of the Timberline Type 256 system, so it anchors the locking workflow for this specific double door setup.
The Timberline CB-256 cylinder body is a surface mounted lock for locking two adjacent doors, so it sits on the door surface rather than inside a routed pocket, which is useful when working with finished cabinet doors. The requirement for a 16.5 mm diameter bore hole defines the main machining step, allowing the installer to match drill bit size or machine settings to that specific diameter. Because the Double Door Cylinder Bodies Mounts in 3/4" Material, the product suits cabinetry and casework built from standard 3/4 inch stock, keeping the bore centered and stable in typical door thicknesses. The 11/16" offset built into the Timberline Type 256 double door lock positions the cylinder face and bolt throw relative to the door edge, which helps align the lock with the TLSP100 and TLSP257 strike plates during layout. This combination of surface mounting and defined boring simplifies planning for consistent door alignment.
The CompX Timberline Type 256 double door lock with 11/16" offset is intended for locking two adjacent doors, so it is suited to cabinet or casework openings where a pair of doors share a center meeting stile. Because it works with either overlay or inset doors, the same CB-256 cylinder body can be applied across different door reveals, from full overlay fronts to traditional face-frame inset designs. The fact that Double Door Cylinder Bodies Mounts in 3/4" Material ties the product directly to common cabinet door thicknesses, which are often built from 3/4 inch panels or frames. As a deadbolt lock in the Locks and Latches category, the cylinder body belongs in assemblies where doors need a positive lock rather than a simple catch, such as storage cabinets or furniture pieces requiring controlled access. Working under the CompX Timberline Lock brand and the CYLINDER BODY, TYPE 256 designation, this lock body fits into Timberline keyed locking layouts that use matching plugs and strikes.
The Timberline Type 256 double door lock requires a 16.5 mm diameter bore hole, so drilling is defined by a specific metric size that can be repeated across multiple doors using a stop or boring machine setup. The 11/16" offset helps position the mechanism relative to the door edge, which supports reliable alignment with TLSP100 and TLSP257 strike plates that are sold separately, reducing trial-and-error fitting during installation. Because the design locks both doors without the use of a spring catch, once the deadbolt is engaged it does not depend on door tension to stay closed, which can reduce call-backs from sagging or slightly warped doors. The surface mounted lock body allows the installer to fasten it directly to the door face, which is helpful when working on finished doors or retrofitting existing cabinets where internal routing is impractical. The key removable in both locked and unlocked positions feature lets the lock body support keyed-different or keyed-alike master plans using separate Timberline lock plugs, so the CB-256 can be integrated into a broader cabinet security layout.
The Timberline Type 256 double door lock works with either overlay or inset doors, so it can be applied to different cabinet door styles using the same cylinder body.
The Timberline Type 256 double door lock is a surface mounted lock body, so it attaches to the door face and avoids full-depth mortising into the door edge.
The CB-256 cylinder body requires a 16.5 mm diameter bore hole, providing a clear drilling dimension for jigs, boring machines, or hand drilling operations.
The Timberline Type 256 double door lock is designed for locking two adjacent doors using a deadbolt action that locks both doors without the use of a spring catch.
The Double Door Cylinder Bodies Mounts in 3/4" Material, aligning the CB-256 with typical cabinet door and casework constructions built from 3/4 inch stock.
The Timberline Type 256 double door lock is locked by turning the key counter-clockwise, and the key is removable in both locked and unlocked positions.
The Timberline CB-256 cylinder body is a CYLINDER BODY, TYPE 256 surface mounted deadbolt that locks two adjacent doors without a spring catch, so it fits applications needing positive door security in typical 3/4 inch material. Its ability to work with either overlay or inset doors and rely on a 16.5 mm diameter bore hole gives installers predictable layout points across different cabinet runs. The 11/16" offset and keyed operation, with the key removable in both locked and unlocked positions, support controlled access planning on multi-door projects. Choosing the Timberline Type 256 double door lock brings a defined drilling dimension, a known offset, and a deadbolt mechanism into one lock body that is ready to pair with matching Timberline strike plates and lock plugs.
