The LiftMaster 41A6569 Safety Sensor Mounting Kit is a replacement/upgrade bracket set designed to properly mount and align the photo-eye safety reversing sensors used on LiftMaster residential garage door openers. It provides the correct mounting interface to secure each sensor at the bottom of the door opening, helping ensure reliable obstruction detection and compliance with UL 325 safety requirements. The kit is commonly used when original brackets are bent, missing, or incompatible with the track or wall configuration, and it supports precise left/right and vertical alignment so the sensor LEDs can lock on for normal operation.
Engineered for LiftMaster openers equipped with infrared safety reversing sensors (typical on most Chamberlain Group residential models manufactured since 1993), the 41A6569 kit is also widely used on compatible Chamberlain and Craftsman openers that use the same style photo eyes. This is a mounting kit only; sensors are not included. Installation is straightforward for a trained homeowner or technician: disconnect power, mount the brackets to the vertical door track or adjacent structure at both sides of the opening, attach and aim the sensors so they face each other, and adjust until the indicator lights show proper alignment. For safety, install the sensors no higher than 6 inches from the floor and follow the opener’s owner’s manual for final testing and verification. This dependable replacement part helps restore correct sensor positioning for residential applications where consistent alignment and dependable obstruction detection are essential.
