These are a great alternative to our GRI 4532L Overhead Door Contact. Instead of having the contact on the floor where it could get run over by vehicles causing damage; this contact fits on to the track of the garage door.

Features

• For Mounting on Door Tracks - Better to have than on the floor.
• Decreases damage.
• 4 way adjustable magnet bracket
• Wider Gap for reduced false alarms
• Installs better and faster than standards overheads
• Closed Loop, open loop and SPDT types (We however only carry the closed loop type)
• Armored Cable is Standard
