The Marantec 85678 Safety Sensor Extension Bracket Kit is an OEM mounting solution designed to reposition Marantec garage door opener photo eyes when the standard track location is obstructed. Ideal for new installs or retrofits, these brackets shift the safety sensors outward to clear track hardware, struts, low headroom double-track setups, or other obstructions, helping maintain a clean line-of-sight for the infrared beam. The kit is intended for use with Marantec safety sensor heads used on compatible Marantec openers and does not include the sensors themselves.
Use this replacement and upgrade kit when you need extra clearance to align the photo eyes properly for UL 325-compliant operation. Installation is straightforward: mount the brackets to the door track or jamb in place of the standard clips, attach the photo eyes to the extensions, align the lenses until the indicator LEDs show a solid connection, and test the reversal system per the opener’s manual. For residential garage doors, install the photo eyes so the beam is no more than 6 inches above the finished floor. This Marantec OEM bracket set supports reliable safety sensor placement and beam alignment in situations where direct-to-track mounting isn’t feasible.
