The new extended gap series was specifically developed in response to installer request for a magnetic contact that would work on loose fitting, worn, or damaged overhead doors. It has an expanded area of activation which was designed for doors that don™t return to the exact or approximate position upon closure.
Ideally, the installer should determine 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. All mounting hardware including lead anchors is provided as well as a mounting bracket (NPNB-1S-12) for the actuating magnet. A 1/4™ masonry bit is required for lead anchor installation.
