Quarter Turn

Showing 1–18 of 286 results

Quarter turn latches engage and disengage their keeper with just a quarter turn of a cam. Many types of quarter turn latches are available; however, they all function similarly. The keys or tools required to unlock them come in a wide variety of shapes, which helps to reduce tampering by unauthorized individuals.

Each quarter turn latch made by Sierra Pacific Engineering and Products comes with an integrated O-ring that creates a water-resistant seal. This helps to ensure a more robust enclosure, protecting the contents from moisture and dust, and making quarter turn latches useful in a range of industries, such as RVs, HVAC and electronic enclosures.

Some of the many quarter turn latch designs available from SPEP are slotted arrow, hex, recessed hex, thumb turn, 7 mm square, 8 mm square, key lockable, padlockable, L handle, double bit and triangular. To go with the latches, we offer dozens of sizes and styles of cams, as well as other accessories, such as keys, padlocking cups, finger pulls and dust covers.

Our quarter turn latch housings and plugs are made of black or chrome-plated die-cast zinc, stainless steel, or black thermoplastic.

If none of the latches in our extensive selection meets your exact requirements, please contact our team of experienced engineers for help with modifying one of our designs or creating a new one.
