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.

Anti-rattle cam latches versus push-button rims

221100-1: 316 stainless

A compact open-mount cam latch for cabinets, doors and hatches; it uses four #10 flat-head fasteners.

222110-1: chrome brass

A larger version of the anti-rattle cam concept. Verify its own 4-inch A and 2-inch D measurements.

225310-1: push-button rim

A different, mortise-mounted mechanism with a square button, for doors up to 1 inch thick.

Strike choices matter

The 225310-1 display version includes flat and 90-degree strike plates. Replacement strike plate MPNs are 224320 and 224321.

Sea-Dog latch dimensions and fasteners

The A, B, C and D dimensions are the reference labels from Sea-Dog's individual product drawings. Check the original drawing orientation before using a value for a mounting cutout.

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

  1. Match the latch mechanism and material to the original installation: center-tensioning surface cam or mortise-mounted button.
  2. Compare the specific manufacturer's A–D dimensions and the available door or hatch clearance before drilling.
  3. For the anti-rattle latches, choose the correct four #10 flat-head mounting screws and an appropriate locking arrangement if needed.
  4. 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.
