CompX Timberline CB-311 glass door lock gives you a surface mounted lock for locking doors on bypassing or showcase units where straightforward security is required. The CB-311 cylinder body only design focuses on the core locking function, which suits installations where you are standardizing on a specific cylinder body and selecting plugs separately. All locks have 3/4 inch long cylinders, so you get a consistent reach through typical glass or panel thicknesses that fall within the stated up to 3/8 inch range. The lock requires a 16.5 mm diameter bore hole, which defines your drilling layout and keepers when planning door fabrication. Bright nickel finish on the body presents a clean, neutral look that coordinates with common bright nickel lock plugs.
This CB-311 glass door lock is a bore style, vertical mount design, so the cylinder body installs in a drilled 16.5 mm hole with the lock positioned vertically on the door surface. The surface mounted format means you plan your layout around the cylinder centerline and strike location rather than cutting pockets, which simplifies door preparation on glass or thin panels. All locks have 3/4 inch long cylinders, so when working with doors up to 3/8 inch thick the remaining cylinder depth provides the working space for the chosen lock plug and strike engagement. Bright nickel finish can be paired with matching bright nickel lock plugs, referenced by TLLP100, to keep a consistent appearance on the exposed face. Vertical mount orientation supports clear alignment of the cam with the mating strike in typical showcase door runs.
The CompX Timberline CB-311 glass door lock sits in the Bypassing and Showcase Door Locks class, so it is suited to showcase and similar door arrangements where a surface mounted lock is appropriate. Its cylinder body only format works in setups where the lock plug and strike are selected separately, which is useful when standardizing plug keying or finish across multiple doors. The product description notes use on doors up to 3/8 inch thick, aligning with many glass showcase panels while staying within the 3/4 inch cylinder length. Because the lock is surface mounted and uses a 16.5 mm bore hole, it is a practical option on glass where through-drilling for a clean cylinder seat is preferred over more invasive edge work.
The CB-311 cylinder body uses 180 degree key rotation, so the locking action moves from locked to unlocked in a predictable half-turn that makes operation straightforward for staff or customers. Key removable in both locked and unlocked positions means the same cylinder body can support workflows where the key remains with staff or stays at the lock depending on how access is managed. Tough nylon housing supports the cylinder in the 16.5 mm bore, so the body is stabilized within the door and helps the lock maintain position relative to the strike over repeated cycles. Bright nickel finish on the lock body gives an appearance that coordinates with bright nickel lock plugs such as those referenced under TLLP100, which helps keep a uniform look across doors using this cylinder body only part. In daily use, the combination of defined cylinder length, specified bore size, and vertical mount layout supports consistent engagement between the lock and the separately ordered strike.
