CompX Timberline CB-307 Glass Door Lock Use

CompX Timberline CB-307 glass door lock is a bore style cylinder body for swing style glass doors, giving glass cabinets a keyed locking point directly through the panel. The lock is designed for swing style doors, so the cylinder secures doors that pivot on hinges rather than sliding tracks, which suits many showcase and cabinet layouts. A fully cushioned lock clamping design grips the glass while helping avoid glass damage, so installers can tighten the lock against the panel without stressing the edge. The cylinder body works with a two piece design, where the lock is engineered so the user does not need to assemble the cam, which simplifies handling during installation or replacement. Satin nickel finish on the CB-307 provides a neutral, clean appearance that blends with many contemporary cabinet and display hardware lines.

Key CB-307 Details For Glass Door Projects

• The CB-307 glass door lock is a bore style cylinder body that mounts through a drilled hole in the glass, so the door itself becomes the lock point, helpful when the cabinet frame offers limited mounting surface.
• The lock is designed for swing style doors and fits vertically mounted glass doors up to 3/8 inch thick, allowing use on common showcase glass thicknesses without altering the panel.
• A fully cushioned lock clamping design helps avoid glass damage as the lock tightens, which matters when working near glass edges and corners on finished display pieces.
• The lock uses a two piece design where the user does not need to assemble the cam, reducing handling steps and keeping installation focused on positioning and mounting the cylinder in the bore.
• A satin nickel finish cap is attached to the lock to give a finished appearance, so the visible side of the cylinder presents a clean, consistent look on the cabinet face.

Glass Door Lock Bore And Mounting Details

This bore style CB-307 cylinder body requires a 7/8 inch diameter hole bored in the glass, centered 7/8 inch from the edge, so installers can lay out drilling with simple, repeatable measurements. The lock can be horizontally or vertically mounted, with horizontal and vertical mount styles locking to the side or bottom of the cabinet respectively, giving flexibility in how the cam engages the cabinet structure. When vertically mounted in glass doors up to 3/8 inch thick, the CB-307 provides a direct through-glass locking point that does not depend on a wide frame. Cam rotation is specified so the cam must rotate counter clockwise to lock, with an extension of 7/8 inch and a setback of 15/16 inch, helping match the cam throw to the cabinet strike location.

How This Bore Style CB-307 Lock Works

Where The CB-307 Glass Lock Is Applied

The CB-307 glass door lock belongs to the bypassing and showcase door lock class, placing it in typical display cabinet and showcase applications where visibility and controlled access are both required. Designed for swing style doors, this cylinder body suits hinged glass doors on cases, display cabinets, and similar furniture where the panel opens outward. Vertically mounting in glass doors up to 3/8 inch thick lets fabricators and installers work with standard glass stock while still adding keyed security at the door edge. Because the lock clamps directly to the glass using a fully cushioned interface, it creates a secure hold on the panel while helping protect the glass surface during tightening. Horizontal and vertical mount styles lock to the side or bottom of the cabinet, so the same core geometry supports different cabinet layouts and strike locations. The attached satin nickel finish cap presents a consistent face on visible display fronts, supporting cabinets where aesthetics and hardware alignment both matter.

Lock Geometry For Repeatable Cabinet Results

The bore style design of the CB-307 specifies a 7/8 inch diameter hole centered 7/8 inch from the glass edge, giving clear layout dimensions for drilling jigs and production templates. This consistent geometry helps cabinet shops repeat the same lock position across multiple doors, keeping reveals and cam engagement points aligned from cabinet to cabinet. The lock operates with a cam that must rotate counter clockwise to lock, with an extension of 7/8 inch and a setback of 15/16 inch, so the throw distance and retracted position are known values when designing or locating a strike plate. Because the lock uses a two piece design where the user does not need to assemble the cam, the cylinder and cam relationship is fixed from the manufacturer, which helps maintain consistent cam orientation and extension. The fully cushioned clamping arrangement supports tightening the lock against the glass while helping avoid point pressure on the bore edge, important for long term use in showcases that are opened and locked frequently.
