CompX Timberline CB-301 Glass Door Lock Use

CompX Timberline CB-301 glass door lock gives swing style glass doors a dedicated locking point, so display or cabinet openings can be secured without adding frame-mounted hardware. The lock is designed for swing style doors, so it matches common glass door motion in showcase and cabinet applications where doors pivot rather than slide. A fully cushioned lock clamping design protects the glass during locking, reducing the risk of edge chipping when the clamping force is applied against the panel. The lock uses a bore style layout, so it seats through a machined hole in the glass instead of relying on edge clips, which helps hold alignment around the cylinder. Bright nickel finish on the cylinder body presents a clean, finished appearance at the door surface, which matters on visible retail or office displays.

Key CB-301 Details That Support Glass Work

• Designed for swing style doors, this lock aligns with typical pivoting glass door layouts, so the cylinder action works naturally with the way the door opens and closes in a cabinet or showcase.
• Fully cushioned lock clamping avoids glass damage by spreading the clamping force, which is important when tightening against tempered or thinner glass edges in daily use.
• Horizontal and vertical mount styles lock to the side or bottom of the cabinet, respectively, allowing the same lock family to address different cabinet geometries and framing conditions.
• The lock has a 2 piece design for quick mounting, so the user does not need to assemble a cam, which simplifies installation steps and saves assembly time at the bench.
• Vertical mounting in glass doors up to 3/8 inch thick supports a defined glass thickness range, so door panels within that range can be drilled and locked without changing to another body size.
• The lock requires a 7/8 inch diameter hole bored in glass, centered 7/8 inch from the edge, which gives clear drilling dimensions for glass fabrication and layout work.

Glass Bore And Mounting Geometry For CB-301

The CompX Timberline CB-301 glass door lock uses a 7/8 inch diameter bore through the glass, centered 7/8 inch from the edge, giving straightforward numbers for layout on the door corner. This bore style approach positions the cylinder body solidly in the glass, which supports repeatable alignment between the key, cam position, and strike location. Vertical mounting in glass doors up to 3/8 inch thick defines the panel thickness the body is built around, which helps maintain clamping performance once the cushioned components are tightened. Horizontal mount styles in the same family lock to the side of a cabinet and vertical mount styles lock to the bottom, so the mounting plane can be chosen to suit the cabinet framework while using consistent locking geometry.

Using The CB-301 In Bypassing And Showcase Cabinets

Where This CB-301 Glass Door Lock Fits Best

The CompX Timberline CB-301 glass door lock is part of the Bypassing and Showcase Door Locks class, so its geometry and action are aimed at display and cabinet environments. Designed for swing style glass doors, it supports pivoting door panels in showcases where a clean glass front is preferred over framed doors. Vertical mounting in glass doors up to 3/8 inch thick allows use on common glass thicknesses found in many commercial display cases and residential cabinets. Horizontal and vertical mount styles are described as locking to the side or bottom of the cabinet, respectively, so the CB-301 family can be matched to cabinets with different framing or rail layouts while maintaining the same basic lock function. Bright nickel finish on the cylinder body gives a finished appearance at the lock location, which is useful where the hardware is directly in the customer sightline.

Lock Motion, Cam Travel, And Repeatable Results

The CB-301 glass door lock uses a 2 piece design for quick mounting so the user does not need to assemble a cam, meaning the cam interface is predefined at the factory and the field work focuses on positioning and tightening. The lock requires a 7/8 inch diameter hole bored in glass, centered 7/8 inch from the edge, which sets both the radial and edge spacing so the cam can reach a strike without trial-and-error positioning. Cam motion is specified to rotate counter clockwise to lock with an extension of 7/8 inch and a setback of 15/16 inch, which defines how far the cam projects and retracts in relation to the cylinder centerline. That extension and setback detail matters when laying out the mating strike location, because it tells how far the cam will travel into the strike pocket and how much clearance is available when unlocked. A finish cap is attached to give a finished appearance, so once installed the lock face and surrounding trim read as a complete unit on the door surface.
