Genie 37220R Replacement Safety Beams;

The Genie Replacement Safety Beams replace most Genie infra-red photo cell systems. These are the newest and most advanced sensors Genie now makes, replacing all previous sensors except the first generation ISR-3 wire connection beams. These will not work with openers not originally equipped with infra-red sensors. The GSTB-BX beams have screw terminal connections and come with mounting brackets and complete mounting and wiring instructions.;;These sensors have screw terminals instead of plug-in or push-in connections for the sensor wires. The pig-tail sensor plug is not needed to connect these sensors to the sensor wires.
