Know the moment.

The GRI 4532DL-36 is a wired overhead door contact switch with a mounting bracket and a 36″ stainless steel armored lead. It reports the open or closed state of an overhead door to an alarm system, and it suits both DIY and professional installers. The cast aluminum case and hermetically sealed reed switch are built for harsh environments, and the case lets you swap in a new contact without redrilling.
