LiftMaster 97LM Protector System Mounting Bracket Extension
The LiftMaster 97LM Protector System Mounting Bracket Extension is a safety sensor mounting accessory used to adjust the position of compatible garage door photo eyes. It can help add clearance, height, or depth where the standard bracket position does not allow proper alignment.
This bracket extension is used with compatible LiftMaster-family safety reversing sensor systems. It is not a replacement for the photo eye sensors themselves.

Technician Note
Bracket extensions should be used to achieve a clean, secure, aligned sensor installation. If photo eyes are constantly going out of alignment, inspect the track, bracket mounting surface, vibration, loose fasteners, and sensor wiring.
Before Ordering, Confirm
- The existing sensors are compatible Chamberlain Group style photo eyes
- The problem is bracket position, not a failed sensor
- The required extension height or depth matches the installation
- The package quantity matches the job requirement
- The safety sensors will remain properly aligned after installation
Professional Advisory
Garage door safety sensors are part of the opener's entrapment protection system. Do not bypass, tape, defeat, or remove photo eyes to make the opener close. If the door will not close after bracket work, correct the alignment or wiring issue before returning the opener to service.
