Perko 0931DP1BLK Flush-Mount Locking Latch, Black, Offset Cam Bar 3/8 to 3 Inches

The Perko 0931DP1BLK is a flush-mount locking latch built for cabinet doors, hatches, and access panels aboard a boat. The lock sits flush with the surface once installed, using an offset cam bar that adjusts from 3/8 inch to 3 inches to reach the strike, along with a flexible polymer strike that absorbs play and lets the latch seat smoothly even if the door has minor movement or misalignment. The body is molded in black plastic with a chrome plated zinc alloy lock mechanism, and the stem and lock nut are stainless steel for corrosion resistance in a marine environment.

Installation is straightforward: the lock mounts into a 2 inch diameter hole and uses a 2-1/2 inch by 2-1/2 inch face plate to cover the cutout, making it a practical retrofit for existing hardware of the same footprint. It is designed for doors and panels from 1/4 inch to 1-1/8 inch thick. Each lock ships with 2 keys so a spare is on hand from the start.

This is the black, keyed-lock version with the offset cam bar and flexible polymer strike. Perko also offers this same lock in white, in a version with an adjustable cam bar, and in a version with a straight cam bar for a shorter reach, as well as a non-locking latch counterpart, so the door hardware on a boat can be matched by finish, throw style, and whether a key is needed.
