CompX Timberline Lock Cylinder Body, Horizontal Mount with Setback 3/32" Off-Set Cam, Cam Ext 1-1/4" - CB-183

CompX Timberline Lock Cylinder Body For Cabinet Security

CompX Timberline lock cylinder body CB-183 is a cam lock cylinder body designed for horizontal mounting, so it supports typical cabinet and casework layouts where the lock sits sideways across the door or drawer rail. The cylinder body uses a 3/32 inch off-set cam, which positions the cam slightly away from the cylinder centerline, helping the cam meet the strike properly in standard cabinet constructions. A cam extension of 1-1/4 inch gives the lock reach to engage a strike that sits back from the bore, important when working with face frames or overlay conditions. The cylinder body provides 180 degree rotation, so the key turn sweeps a half-circle, moving the cam from fully unlocked to fully locked in one motion. This is a Type 183 cylinder body, which ties part selection directly to the manufacturer reference number CB-183 during layout and ordering.

Key Cylinder Body Details That Support Installers

• This cylinder body is classified as a cam lock, so it serves as the rotating core that moves the cam to secure cabinet doors or drawers in woodworking projects.
• A 16.5 mm diameter bore hole requirement defines the drilling layout, letting installers set up boring equipment or jigs to the exact metric size before production runs.
• The lock is designed to mount in 3/4 inch thick material with a 3/4 inch long cylinder, matching common cabinet stock thickness and simplifying planning for door and drawer fronts.
• Locks must be installed to lock in a counter clockwise position, so the rotation direction of the key and cam is defined in advance for consistent shop and field work.
• The horizontal mount orientation with off-set cam supports typical cabinet layouts where the cylinder must align with a strike along the rail rather than in a vertical configuration.

Mounting And Bore Details For CB-183 Installation

This CompX Timberline cylinder body mounts horizontally, which shapes how the cylinder face and cam sit relative to the cabinet edge during layout. The lock requires a 16.5 mm diameter bore hole, so the primary drilling operation is a single metric hole that accepts the cylinder body. The design targets 3/4 inch thick material with a 3/4 inch long cylinder, aligning the cylinder length to common cabinet door and drawer front stock so the face sits correctly at the outside surface. With the lock set to operate through 180 degree rotation and to lock in a counter clockwise position, the direction of the key turn and cam travel is fixed, helping maintain a uniform user experience across multiple lock locations in the same installation.

Using The Type 183 Cylinder Body In Cabinet Work

Where The CB-183 Cylinder Body Is Typically Applied

This CB-183 cylinder body is part of the CompX Timberline lock family in the cam locks class, so it fits projects where rotating cams are used to secure cabinet or casework openings. The horizontal mount design means the lock body is oriented so the cylinder axis runs parallel to the cabinet rail, a layout commonly used on doors or drawers where the strike is located along the same line. Because the lock is built around a 3/4 inch long cylinder intended for 3/4 inch thick material, it suits cabinet constructions based on that thickness without adding extra build-up to bring the cylinder face flush. The 3/32 inch off-set cam and 1-1/4 inch cam extension give the moving part enough reach and offset to contact a strike located slightly away from the bore center, which is useful when the locking edge sits behind a face frame or overlay front. The Type 183 reference connects this body to that specific geometry, so repeating the same part number keeps future builds and replacements aligned with the original configuration.

Details That Help Achieve Consistent Lock Operation

The 16.5 mm bore hole requirement ties directly to the way the cylinder body seats in the panel, so maintaining that diameter keeps the body centered and stable during rotation. Because the cylinder is sized for 3/4 inch thick material, the threaded body length is matched to that thickness, which helps the cylinder shoulder register cleanly at the front face without projection that could interfere with trim or hardware around the lock. The 180 degree rotation defines the travel of the cam between open and closed positions, so the strike layout can be planned with the full sweep of the cam in mind. With locks specified to lock in a counter clockwise position, the installer can orient the cam at the correct starting angle, knowing the key turn will always bring the cam into engagement in the same direction. The 1-1/4 inch cam extension works with the off-set geometry to reach strikes positioned back from the edge, reducing the need to move strikes closer to the bore in standard 3/4 inch cabinet work.

Common Questions About The CB-183 Cylinder Body

Selecting The CB-183 Cylinder Body For Your Project

The CompX Timberline lock cylinder body CB-183 combines a 16.5 mm bore requirement, 3/4 inch material design, and horizontal mount layout, so it fits naturally into cabinet projects built around standard 3/4 inch stock. Its 180 degree rotation, counter clockwise locking action, and 3/32 inch off-set cam work together to move a 1-1/4 inch cam extension into the strike path in a defined arc. For projects matching these dimensions and geometry, choosing the Type 183 cylinder body aligns drilling, thickness, and cam reach with the lock layout from the start.
