CompX Timberline CB-175 Sliding Door Push Lock Cylinder Body, Mounts in 3/4 Material, CB-175

CompX Timberline CB-175 Sliding Door Lock Use

CompX Timberline CB-175 sliding door lock is a cylinder body for locking sliding, bypass type doors, so it gives showcase and bypass door installations a dedicated locking point. The cylinder body is listed as Type 175, which helps match it to CB-175 plugs and strikes in the same series for a consistent locking setup. The lock mounts in 3/4 material, so it suits door panels built from 3/4 inch stock commonly used in woodworking and fixture construction. It requires a 3/4 inch diameter hole in the front door for the cylinder, which defines the boring operation and helps align drilling to the correct size on the first pass. Pushing in the cylinder locks doors, with or without key, so the locking action can be engaged from the face for quick securing of sliding panels. A 45 degree key rotation allows the cylinder to pop back out to unlock doors, giving a clear visual and tactile indication that the lock is open and the doors can move.

Key Details That Support Sliding Door Work

• The cylinder body is for locking sliding, bypass type doors, so it is suited to showcases and similar bypass applications where panels move past each other rather than swinging on hinges.
• The CB-175 cylinder body mounts in 3/4 material, which matches common door thicknesses and simplifies material selection when planning door construction or retrofitting existing sliding units.
• The front door needs a 3/4 inch diameter hole for the cylinder, setting a clear boring size so installers can produce a clean, right-sized opening with standard bits and avoid oversize or undersize cuts.
• Pushing in the cylinder locks doors, with or without key, so users can secure cabinets quickly without always using the key, which can speed daily open-and-close routines.
• A 45 degree key rotation allows the cylinder to pop back out to unlock doors, so unlocking is controlled and repeatable, with the extended cylinder showing that the sliding panels are ready to move.
• The lock throw length is 5/16 inch, providing a defined travel distance for the locking bar engagement that helps align strikes for positive catch engagement on sliding door edges.

Mounting And Hole Details For CB-175 Fit

The CB-175 cylinder body mounts in 3/4 material, so door construction can use standard 3/4 inch panels common in cabinetry and display fixtures. The unit requires a 3/4 inch diameter hole in the front door for the cylinder, defining the bore size so drilling setup is straightforward with standard bits. The lock throw length is 5/16 inch, giving the travel available for the locking action and helping position the strike to catch within that length on the bypass door edge. An optional TLBZ110 finish cup for the back door requires a 1/2 inch hole, so when that finish cup is used the back panel drilling size is defined for a neat finished opening around the rear engagement point.

Using The Type 175 Cylinder Body In Practice

Where The CB-175 Cylinder Body Is Applied

The cylinder body, Type 175, is for locking sliding, bypass type doors, so it fits into installations where doors move along tracks rather than hinging, such as showcases or bypass cabinets. Mounting in 3/4 material means it aligns well with door panels made from 3/4 inch sheet goods commonly used in woodworking shops, helping maintain consistent edge profiles and structural strength. The front door requires a 3/4 inch diameter hole for the cylinder, which means the lock occupies a substantial section of the stile area and gives a solid seat in the panel. With a 5/16 inch lock throw length, the lock delivers a measured projection to reach a mating strike on an adjacent sliding panel. The optional TLBZ110 finish cup for the back door uses a 1/2 inch hole, so the rear door opening is smaller and more compact, giving a trimmed look where the lock engages the back panel.

How CB-175 Operation Supports Repeatable Locking

The CB-175 cylinder body uses a push-in cylinder to lock doors, with or without key, so the motion to secure sliding panels is the same every time and does not depend on turning the key to set the locked state. A 45 degree key rotation allows the cylinder to pop back out to unlock doors, so unlocking uses a short, controlled key turn that moves the cylinder to an extended position and releases the panels. The Type 175 cylinder body works with a lock throw length of 5/16 inch, so the engagement distance is predictable and supports precise placement of the strike for solid contact when the cylinder is pushed in. The product name specifies it as a sliding door push lock cylinder body, which identifies its role as the main locking component in a push-to-lock, key-to-release workflow on bypass doors. The CB-175 designation and Type 175 description help match it with the correct lock plug and strike series in projects that use coordinated parts.

Selecting The CB-175 For Sliding Door Projects

The CompX Timberline CB-175 sliding door lock cylinder body is specified for locking sliding, bypass type doors, so it fits projects using moving panels on tracks.
