CompX Timberline CB-317 Glass Door Lock (up to 3/8 Thick) Cylinder Body Only, Bore Style, Vertical Mount, Satin Nickel, CB-317

CompX Timberline CB-317 Glass Door Lock For Swing Doors

CompX Timberline CB-317 glass door lock is a bore style cylinder body for swing style glass doors, so it provides keyed security at the door instead of relying on external catches. This CB-317 cylinder body is part of the CompX Timberline bypassing and showcase door locks class, so it is suited to cabinets and showcases that need controlled access. The lock is designed specifically for swing style doors, which keeps its operation aligned with common glass door layouts in display and cabinet work. This model vertically mounts in glass doors up to 3/8 inch thick, so it fits many standard showcase glass panels without extra adaptation work. A satin nickel finish is used on the exposed components, giving a neutral, project-friendly appearance that blends with many hinge and pull finishes. The lock uses a two piece design for quick mounting, which simplifies installation steps by keeping the cam assembly work off the installer.

Key Glass Door Lock Details That Support The Job

• The lock is described as a glass door lock in the locks and latches, bypassing and showcase door locks category, so it is intended for cabinet and showcase applications where a keyed point of control is required at the glass panel.
• A bore style, vertical mount cylinder body is specified, so the lock seats through a prepared hole in the glass and clamps around it, creating a secure anchoring point along the door edge for swing door locking.
• The design is stated as a two piece lock clamping system with full cushioning, so the glass is gripped between components instead of being drilled for fasteners, reducing direct stress on the glass at the locking point.
• The finish is satin nickel, and a finish cap is attached to give a finished appearance, so the installed lock presents a clean, uniform face on the cabinet or showcase front while covering the working body.
• The product is identified as cylinder body only with strike plate sold separately, so this part serves as the keyed locking core while the mating strike is selected and positioned to match the cabinet frame design.

Vertical Mount Glass Door Lock Bore And Fit Details

The CB-317 vertical mount design is specified for glass doors up to 3/8 inch thick, so the clamping range is tuned to that glass size and aligns the lock body correctly in the door plane. The lock requires a 7/8 inch diameter hole bored in the glass, centered 7/8 inch from the edge, so drilling layout is clearly defined and repeatable across multiple doors on the same project. Because the lock clamps fully around the prepared bore with cushioning, the glass contact is distributed around the hole instead of at isolated points, which matters when doors are opened and closed repeatedly in service. The bore style layout keeps the lock body centered on the glass thickness, helping maintain even reveals and consistent engagement with the separate strike plate at the cabinet side.

How This Bypassing And Showcase Door Lock Works In Practice

Glass Door Lock Application In Swing Style Cabinets

This CompX Timberline glass door lock is described as designed for swing style doors, so it functions with doors that pivot on hinges rather than sliding tracks, common in many display cabinets and showcases. Horizontal and vertical mount styles in this product family are said to lock to the side or bottom of the cabinet, respectively, and this CB-317 version is the vertical mount type, so it is intended to engage along the side frame of the cabinet when installed on a door edge. The product is listed in the bypassing and showcase door locks class, which places it in applications where contents remain visible through glass and access is controlled by keyed operation. Because it vertically mounts in glass doors up to 3/8 inch thick, it fits many typical showcase doors without modifying the glass thickness, which supports consistent fabrication across a run of casework. The satin nickel finish ties into other satin nickel hardware commonly used on cabinet hinges and pulls, so the visible cylinder can match surrounding hardware choices on the same installation.

Locking Motion, Cam Setup, And Strike Plate Alignment

The lock uses a two piece design for quick mounting, and the user does not need to assemble the cam, so the internal working relationship between cylinder and cam is factory set, saving layout time on the bench. The cam is specified to rotate counter clockwise to lock with an extension of 7/8 inch and a setback of 15/16 inch, so the locking throw and retracted position are clearly defined for planning the strike location on the cabinet frame. These cam dimensions determine how far the cam projects past the door edge when locked and how it clears the strike when unlocked, which is important for smooth operation and to avoid drag on the frame. The separate note that the strike plate is sold separately means the mating part can be chosen and placed to match these cam extension and setback values, allowing the installer to align the strike position with the cabinet geometry. With a 7/8 inch diameter hole bored 7/8 inch from the edge, the lock body centers consistently on the glass, so the cam swing path repeats from door to door, giving uniform engagement across multiple cabinets or pairs of doors.
