37220R Genie GSTB-BX Safe-T-Beam Sensors
Genie's Safe-T-Beam photo-electric garage door opener safety sensors project an invisible infrared beam across the bottom of the garage door opening and can detect anything passing through the beam when the door is closing which will automatically reverse the garage door opener. The replacement GSTB-BX safety sensors work with Genie garage door openers manufactured since 1993 that don't use a 3-pin plug connector at the motor head. The safety sensor kit includes both safety sensors, mounting brackets and instructions. Bell wire for sensors is not included but can be purchased separately.
