The LiftMaster 041A5266-3 safety sensor bracket kit is used to mount and align garage door opener safety reversing sensors at the door opening. These brackets are important because the photo eyes must remain aimed directly at one another for the opener to close normally and reverse if the beam is blocked.
This is a bracket-only kit, not a complete sensor kit. It is commonly connected in parts searches with 41A5034 safety sensor kits and related bracket numbers such as 41A5266-1 and 12D584-1. Customers often need this item when the original sensor brackets are bent, rusted, missing, or will not hold alignment after door track or opener service.
LiftMaster lists 041A5266-3 as discontinued, so the live product should be reviewed for availability and replacement direction. If the customer needs sensors as well as brackets, a complete safety sensor kit may be required instead of this bracket-only item.

If the opener closes only when the wall button is held down, the issue may be sensor alignment, sensor wiring, damaged photo eyes, or brackets that will not hold the beam steady. Do not bypass the safety system.
Safety reversing sensors are required protective devices. If a garage door opener will not close because of sensor trouble, correct the sensor problem rather than defeating or bypassing the sensors.

Yes. If the brackets bend or move, the photo eyes may lose alignment and the opener may reverse or refuse to close.
No. Safety sensors must remain installed and aligned. Replace or repair the sensor mounting issue instead of bypassing the system.
