The Tane 86 overhead garage door contact is a floor mount mini in size. Dimensions are 2 ¼” long by beveled 3/8” high. This allows the installer to mount the contact out of the way in warehouse applications. The overall gap is almost 3 inches with a leeway for the magnet to go 2 inches off center if the door moves in or out as a result of a storm. The contact is bar cast aluminum with no epoxy on the underside to deteriorate over time. The magnet housing is angled to not allow it to be used as a step for closing the door. The TANE-86 comes with commercial grade flexible armored cable. This design allows a unique use for normal doors in commercial applications by mounting the contact on the door frame and magnet on the door, thus making it hard for vandals to abuse. Tane offers a $50 lifetime warranty. For more information go to www.tanealarm.com or call 800 852-5050.
