What are quarter turn cam latches?

For the most part, a quarter turn cam latch functions as a locking mechanism that’s mounted on doors, panels, and drawers. You can find these components in switch boxes, access panels, lockers, and hatches. Comprising a housing, insert, and cam, quarter turn latches are durable and can be used across a wide range of equipment, from office furniture to military hardware.

Quarter turn cam latches get their name from the fact that they require a key, handle, or knob to turn a pawl 90 degrees in order to latch. For added strength, quarter turn receptacles or fasteners are usually added.

Quarter turn cam latches come in either quarter turn lock or non-locking varieties. Another variety is known as a compression latch which operates the same way. The only difference is that this type of latch requires an additional quarter turn to compress a gasket between the panel and the frame to create an airtight seal.

The latches come in several options for different materials and handle constructions. You can choose between a chrome plated and stainless steel quarter turn lock. The handles are made from nylon or plastic polyamide material that can withstand high temperatures and moisture. There are also a variety of finishes to choose from, including black powder coated, die-cast zinc, or chrome plated.

Consisting of low-profile swing handles, tool-operated cam latches can be used for indoor and outdoor applications. They typically consist of a key lock, and some varieties may have a wing knob with padlock fittings.
