Perko Barrel Bolt, Chrome Plated Bronze, 3/8 in Bolt, Bulkhead Keeper

Overview

The Perko 0947 Barrel Bolt is a chrome plated bronze marine barrel bolt for securing small doors, cabinet panels, lockers, and access openings on board. It uses a 3/8 inch diameter bolt and a high impact black nylon bulkhead keeper, giving boat owners a clean latch option for interior or protected hardware locations where fit and smooth operation matter.

This barrel bolt is available in 3 inch, 4 inch, and 5 inch size options, with overall dimensions ranging from 3-7/16 x 1-7/16 inches to 5-1/4 x 1-7/16 inches depending on the selected variant. The bulkhead keeper installs in a 5/8 inch hole, and the included friction pad helps reduce rattle while keeping the bolt movement smooth.

Key features

• Chrome plated bronze body for a polished marine hardware finish on visible cabin, cockpit, or locker installations.
• High impact black nylon bulkhead keeper for use where the bolt needs to engage into a bulkhead-mounted receiver.
• 3/8 inch diameter bolt gives the latch a solid feel for doors, small hatches, cabinet faces, and equipment access panels.
• Bulkhead keeper installs in a 5/8 inch hole, which is useful when checking fit before drilling or replacing existing hardware.
• Friction pad helps control rattle and gives the bolt a smoother sliding action under normal boat vibration.
• Works with #6 screws, allowing the installer to match fasteners to the mounting surface and finish requirements.

Variants

This Perko barrel bolt is offered in three size configurations. The size changes the overall length of the bolt assembly, while the chrome plated bronze body, 3/8 inch bolt diameter, black nylon bulkhead keeper, 5/8 inch bulkhead keeper hole requirement, and #6 screw size remain consistent across the listed variants.

The shorter size suits tighter cabinet or locker layouts, while the longer sizes give more reach across wider gaps or larger door and panel installations. Final fit should be checked against the mounting surface, keeper position, and available clearance for the sliding bolt.

• 0947DP1CHR: 3-Inch size with overall dimensions of 3-7/16 x 1-7/16 inches. This is the most compact option in the range and works well where space around the latch is limited.
• 0947DP2CHR: 4-Inch size with overall dimensions of 4-5/16 x 1-7/16 inches. This mid-size version adds reach while keeping the same narrow mounting width.
• 0947DP3CHR: 5-Inch size with overall dimensions of 5-1/4 x 1-7/16 inches. This is the longest listed option and is better suited to larger doors, panels, or applications needing more bolt travel across the opening.

Installation and fit

Before installation, confirm that the door, frame, cabinet face, or bulkhead has enough flat mounting area for the selected overall size. The keeper location should line up squarely with the bolt so the latch slides without binding, especially on boat joinery that may shift slightly under vibration or humidity changes.

For bulkhead keeper installations, plan for the 5/8 inch hole requirement and check the backside of the mounting surface before drilling. Use fasteners that match the substrate and the surrounding hardware finish, and avoid overtightening into thin panels or trim pieces.

Use cases on board

This barrel bolt is a practical match for owners replacing worn cabin hardware or adding a positive mechanical latch to lockers, cabinets, small access doors, and protected utility spaces. It is especially useful where a simple sliding bolt is preferred over a keyed lock or spring latch.
