Hammond 1437S16B 2-Hole 30.5mm 316 Stainless Pushbutton Enclosure

Built for two 30.5mm operators, the 1437S16B is an extra deep 316 stainless steel pushbutton enclosure from the 1437SS Series. It is designed to accept standard heavy duty oil tight pushbuttons, switches and pilot lights, and provides protection from dirt, dust, oil and water for start/stop pairs and similar two-device stations.

The body is formed from 16 gauge steel with smooth, continuously welded seams and a natural stainless steel finish with a smooth brushed appearance. Captive cover screws thread into sealed wells, and an oil resistant gasket and adhesive seal the cover. There is a bonding stud on the door and a grounding stud on the enclosure. Per the series notes, larger enclosures have internally hinged removable covers that hold open during wiring, while only the 1-hole size is footnoted as not hinged.
