316 Stainless Steel Marine Lockable Barrel Bolt Latch with a Integrated Padlock Hole. This specialized variation of a standard sliding deadbolt is customized for marine environments like cabin entry doors, windows, and companionway hatches where physical security and noise reduction are required simultaneously.
Core Security & Hardware Mechanics
Integrated Lockhole Feature: The critical difference on this specific model is the addition of a pre-drilled hole on the outer edge of the receiver base plate (right side in your photo). When the center barrel slider is pushed completely into the locked position, its main pin passes over this hole. This allows you to loop a padlock cleanly through the frame plate, physically anchoring the sliding rod so it cannot be forced backward by intruders or heavy waves.
Anti-Rattle Tension Spring: Hidden inside the central casing barrel is an internal spring or friction padding system. This design continuously squeezes against the main sliding shaft, keeping it rigid so it does not shake or produce annoying clicking sounds from your boat's engine vibration.
Lost-Wax Precision Casting: The structural body parts are precision wax-cast out of Grade 316 Marine Stainless Steel and hand-polished to a high mirror sheen. This specialized formulation protects the latch from severe pitting and rust degradation caused by ongoing salt spray exposure.
To ensure a perfect match that utilizes your old screw locations without drilling new holes:
Do you know the overall length of the latch mechanism (standard marine configurations are usually 60mm / 2.3 inches or 90mm–110mm / 3.5 to 4.3 inches)?
Will this be mounted on a flush surface, or is there a corner bevel between the door and the frame panel?
