The 1437MSSD is a four-hole, extra deep pushbutton enclosure in 304 stainless steel, sized for 22.5mm operators. As part of the 1437SS Series it is designed to accept standard heavy duty oil tight pushbuttons, switches and pilot lights, and it keeps those devices protected from dirt, dust, oil and water on production lines, pumps and conveyors.

Formed from 16 gauge steel, the body has smooth, continuously welded seams and a natural stainless steel finish with a smooth brushed texture. Captive cover screws fasten into threaded, sealed wells, and an oil resistant gasket and adhesive seal the cover. A bonding stud is fitted on the door and a grounding stud on the enclosure. The series states that larger enclosures provide internally hinged removable covers designed to stay open during wiring; only the 1-hole size is marked as not hinged.
