The LiftMaster 41A5281-1 Extension Brackets for Snappy Sensors are OEM mounting extensions designed to correctly position safety reversing photo eyes when standard brackets won’t clear obstructions or align across the garage door opening. Engineered for LiftMaster “Snappy” style safety sensors, these brackets help offset and project the sensor heads so the infrared beam can be aimed straight across the doorway, even on tracks or jambs with unusual trims, uneven walls, or limited mounting spots. They are commonly used on residential LiftMaster, Chamberlain, and Craftsman openers that utilize the clip-in, Snappy-style sensor design.
Use these extension brackets to achieve proper beam alignment and meet UL 325 placement guidelines near the floor. Installation is straightforward: mount the brackets at each side of the door, attach the Snappy sensors, connect the low-voltage leads to the opener, and adjust until both sensor indicator lights show a solid alignment. No programming is required; simply restore power and verify safe operation. For best results, keep the lenses clean, ensure tight fasteners, and confirm uninterrupted line-of-sight between sensors before operating the door. This OEM replacement accessory is ideal for new installs, replacements, or upgrades where a standard wall or track mount does not provide a clear path for the photo beam.
