Liftmaster 41A5281 Safety Sensor Extension Bracket Kit 041A5281 041A5281-1
The LiftMaster 041A5281-1 safety sensor extension bracket kit gives installers a way to move the safety sensor mounting point off the door track and onto the garage wall. This can be important when the track bracket location is obstructed, when the door track has been replaced, when the original brackets are bent, or when a cleaner wall-mounted alignment is needed.
Safety reversing sensors must be mounted low, aligned correctly, and wired properly for the opener to close the door. These brackets do not replace the sensors; they support the sensor eyes so the invisible beam can stay aligned across the door opening. A poor bracket position can lead to blinking sensor LEDs, intermittent closing problems, or a door that reverses before reaching the floor.
This kit is commonly used with LiftMaster and Chamberlain garage door opener safety sensor systems. Because sensor bracket designs vary by generation, confirm the opener manual, sensor kit, and installation location before ordering.

Technician Note
Do not bend or force safety sensor brackets to make the beam line up. Correct bracket placement, level mounting, and clean wiring are usually what keep the photo eyes stable over time.
Before Ordering Checklist
- Confirm whether you need brackets only or a complete sensor kit
- Check the opener manual for 041A5281-1, 041A5281, or 41A5281
- Verify that the sensor eyes are working before replacing only the brackets
- Confirm the wall mounting location allows proper beam alignment
- Do not bypass safety sensors to make the door close
Professional Advisory
Garage door openers should not be operated without properly installed and aligned safety reversing sensors. If the opener will not close and the sensor LEDs will not stay aligned, have a qualified garage door technician inspect the sensor wiring and mounting.
Important Ordering Warnings

Product Questions and Answers
Does this kit include the safety sensors?
No. This kit includes extension brackets and hardware only. The sending and receiving sensor eyes are separate unless supplied in another kit.
What is the purpose of the extension bracket?
The extension bracket lets the safety sensor mount to the wall instead of the garage door track, which can help with alignment or clearance problems.
Will this work with Chamberlain garage door openers?
It may be used with various Chamberlain garage door opener safety sensor setups when the opener parts diagram calls for 041A5281-1, 041A5281, or 41A5281.
Can I use this to bypass a bad safety sensor?
No. Brackets only hold the sensors in position. Safety sensors must remain connected, aligned, and working properly.
Why is my door still reversing after replacing brackets?
The sensor eyes may be misaligned, dirty, wired incorrectly, damaged, or the door may have a separate travel or force issue.
