Protect the biggest entry into your home - the garage door - with these great contacts from GRI. Drive right over 'em - they're built from 6063 T5 aluminum to withstand up to 20,000 lbs. of crushing force without damaging the sensor!
The new G.R.I. extended gap series was specifically developed in response to requests for a magnetic contact that would work on loose fitting, worn, or damaged overhead doors. The G.R.I. 250WG has an expanded area of activation which was designed for doors that donít return to the exact or approximate position upon closure.
To install, determine the total travel from left to right and from front to back. Locating the center position in both directions should determine the best placement of the switch.
Standard switch length is 7 1/2" with a 36" armored cable lead, and all mounting hardware including lead anchors is provided as well as one S-12 'L' mounting bracket for the actuating magnet. A 1/4" masonry bit is required for lead anchor installation.
