Sierra Pacific Engineering & Products (SPEP) has just released a new line of fixed grip quarter turn latches with unique new aesthetics. Parts feature a large “mushroom head” plug, which is sleek, low profile, and comes in both matte black powder coat and textured chrome finishes. Nitrile face gaskets and internal o-rings make them water-tight and perfect to use for protecting electrical equipment per NEMA & UL type 12 or 4 industrial enclosure requirements (IP65 ingress protection seal).

Each of the three tool activated styles (slotted, 8mm square, & 7mm triangle) features a directional indicator dot on the face to let you know which way the cam is pointing even when the door is closed. Various zinc plated offset cams snap into place with the included detent washer and the two available body lengths (16mm & 24mm) allow them cover a wide array of possible grip ranges. Parts fit into the industry standard installation cut-out and can be easily swapped out with older quarter turns to modernize the look of your product.

Sierra Pacific Engineering & Products is excited to announce the release of our new hand-polished, stainless-steel latches, to our already popular 6-Dash lineup. These new latches are 316 stainless-steel, making them ideal for both indoor and outdoor applications. They come in both locking (two ringed keys included) and non-locking versions. The flush mount design and concealed mounting hardware give these latches a simple, clean, look. Ideal for the emergency vehicle (fire trucks, ambulances, etc.) and boat industries, as the clean, flush design will not get caught up on anything, allowing you to focus on the task at hand.

SPEP offers 8 different versions of this 316 SS latch, to accommodate a wide range of panel thicknesses, from .079 to .866 inches. Each one of these high-quality latches comes with mounting screws, a mounting bracket, and a keeper/strike plate. In addition to the stainless-steel models, this latch is available in all the same sizes, in a polished / chrome plated, die cast zinc version. Our new latches are in stock and ready to ship.
