INSTALLING THE BRACKETS

Be sure power to the opener is disconnected. 

Install and align the brackets so the sensors will face 
each other across the garage door, with the beam no 
higher than 6" (15 cm) above the floor. They may be 
installed in one of three ways, as follows.

Garage door track installation (preferred):

•  

Slip the curved arms over the rounded edge of 
each door track, with the curved arms facing the 
door. Snap into place against the side of the track. 
It should lie flush, with the lip hugging the back 
edge of the track, as shown in Figure 1.

If your door track will not support the bracket 
securely, wall installation is recommended.

Wall installation (Figure 2 & 3): 

•  

Place the bracket against the wall with curved 
arms facing the door. Be sure there is enough 
clearance for the sensor beam to be unobstructed. 

•  

If additional depth is needed, an extension bracket 
(See accessories) or wood blocks can be used.

•  

Use bracket mounting holes as a template to 
locate and drill (2) 3/16" diameter pilot holes on the 
wall at each side of the door, no higher than 6" 
(15 cm) above the floor. 

•  

Attach brackets to wall with lag screws 
(Not provided).

•  

If using extension brackets or wood blocks, adjust 
right and left assemblies to the same distance out 
from the mounting surface. Make sure all door 
hardware obstructions are cleared.

Floor installation (Figure 4): 

•  

Use wood blocks or extension brackets (see 
accessories) to elevate sensor brackets so the 
lenses will be no higher than 6" (15 cm) above the 
floor.

•  

Carefully measure and place right and left 
assemblies at the same distance out from the wall. 
Be sure all door hardware obstructions are 
cleared.

•  

Fasten to the floor with concrete anchors as 
shown.
