Sea-Dog Marine Door & Cabinet Latches: Anti-Rattle vs Push Button
Choose a marine cabinet or hatch latch by how it closes, how it mounts and the space available. Sea-Dog offers open-mounted anti-rattle cam latches in stainless and chrome-plated brass, plus a mortise-mounted square push-button rim latch for cabinetry. Compare exact model numbers before replacing an existing fitting.

Replacement strike plates are separate parts
The Sea-Dog 225310-1 display version includes flat and 90-degree strike plates. For replacement parts, the flat strike is 224320 and the angled strike is 224321. The manufacturer lists hole spacing of 1-7/8 inches for the flat plate and 1-3/16 inches for the 90-degree plate. These are not replacements for the anti-rattle cam mechanism.
Both anti-rattle latches include a locking hole for a padlock shank up to 1/4 inch. Mounting fasteners are not included with the listed latch assemblies.
Before selecting a new latch
- Match the latch mechanism and material to the original installation: center-tensioning surface cam or mortise-mounted button.
- Compare the specific manufacturer's A–D dimensions and the available door or hatch clearance before drilling.
- For the anti-rattle latches, choose the correct four #10 flat-head mounting screws and an appropriate locking arrangement if needed.
- For the 225310-1 button latch, verify a suitable door thickness up to 1 inch and select the correct flat or 90-degree strike position.
