CAM & Compression Latches

Cam and compression latches have several important specifications that determine fit. To get the right latch, it’s important to understand the terminology: Read More

Hole Size or Cutout Size

Virtually all boat compartment latches are recessed into a cutout for mounting. The diameter of the cutout is the cutout size or hole size. Common sizes are 2” cutout, 2-1/2” cutout, and 2-3/4” cutout. A few very large compartment latches use a 3” cutout.

Face Diameter or Width

The size of the visible “face” of a boat compartment latch is different from the cutout size. If you’re replacing an existing latch, make sure you’re matching the correct dimension.

Panel or Door Thickness

This is the range of thickness of the hatch or door your boat cam latch can be mounted in. These ranges differ quite a bit. Make sure you select a latch that’s compatible with your hatch or door.

Grip Range

This is a measurement of the distance from the surface of the hatch or door where the boat latch is mounted to the pawl, cam, or “catch.” Most compression and cam latches are supplied with several different cams to fit a wide range of grip measurements.

Cam Length

This is the length of the cam, pawl, or catch and determines how far from the edge of the hatch or door the latch can be mounted.

Although they function in essentially the same way, a cam latch (also commonly called a lift and turn latch) and a compression latch have some key differences. Read More

First, most compression latches are waterproof, while most lift-and-turn latches are not. This refers to the latch itself, as opposed to the seal around the lid. If you pour water onto a cam latch, it will drain through the latch body.

Second, marine compression latches compress or pull the hatch or door tightly against its frame for an even drier compartment. For dry storage compartments, pressurized livewell lids, and other applications where water- and air-tightness is important, a quality compression latch is the best choice.

A cam latch is secured by turning a handle which causes a cam to rotate behind the mounting surface of the door or hatch cover, therefore holding it closed. A compression latch uses a spring-loaded trigger and catch, they are closed by pushing down on the latch and opened by lifting the handle which releases the latch.

A marine cam or compression latch is a type of latch designed to secure hatches, doors, panels, and other items in a marine environment. They are designed to be water-resistant and corrosion-resistant, making them ideal for use in boats, yachts, and other marine vessels.

The main benefit of using a marine cam or compression latch is that it does an especially good job holding the hatch or door in place in rough marine situations. It is designed to be water-resistant and corrosion-resistant, making it ideal for use in marine environments.

Yes, marine cam and compression latches are relatively simple to install. They typically come with instructions and can be installed with basic tools. Additionally, most latches come with mounting hardware for easy installation.

Yes, marine cam and compression latches are available in a variety of sizes and styles to fit different applications. Most manufacturers offer a range of sizes and styles, so you can find the right latch for your needs.
