🗎 Product description from the manufacturer spec sheet
The SECO-LARM Enforcer SM-226RQ is an overhead door-mount magnetic contact for large doors and gates where regular contacts are difficult to mount. The closed-loop switch is contained in a curved, low-profile weatherproof die-cast aluminum housing for surface mounting on a garage floor — heavy vehicles can cross over without damaging it — with a 2-3/4 in (70 mm) gap and 24 in wire leads enclosed in a stainless-steel armored cable. The magnet is enclosed in epoxy inside a round-backed aluminum housing that mounts directly to the door.
