LiftMaster 041-0155-000 Safety Sensor Brackets are genuine OEM mounting brackets engineered to hold and align the Protector System photoelectric safety sensors used with LiftMaster garage door openers. Installed near the bottom of the door opening on both sides, these brackets secure the photo eyes to the door track or adjacent surface so the infrared beam remains properly aimed. They are an ideal replacement part when existing brackets are bent, missing, or no longer holding sensors securely, helping restore reliable obstruction detection for residential garage door systems that use LiftMaster, Chamberlain, or Craftsman openers with compatible safety sensors.
Designed for straightforward installation, the brackets position the sensors close to floor level to meet safety requirements and maintain a clear beam path. Proper alignment is confirmed when the sensor indicator LEDs show a steady state according to the opener’s manual. Use low-voltage wiring routed to the opener’s sensor terminals, keep the beam line unobstructed, and avoid mounting where direct sunlight may interfere with operation. This part supports common maintenance and upgrades of LiftMaster’s Protector System and is suitable for residential applications; always verify opener and sensor compatibility by matching part numbers in the product manual before purchase and installation.
