The Genie 36773S.S Carriage Assembly for 8’ doors is a genuine OEM replacement trolley (also called a traveler) for select Genie residential garage door openers configured with an 8-foot rail. The carriage travels along the opener rail to push and pull the door via the door arm and includes the standard Genie quick-release mechanism for manual operation when needed. Replacing a worn or damaged trolley restores smooth, reliable travel and proper engagement with the opener’s drive system.
This replacement part is specific to opener rails set up for 8’ doors; confirm compatibility by matching part number 36773S.S to your opener’s parts diagram or product label. Installation generally involves disconnecting power, pulling the emergency release, removing the old trolley, sliding the new carriage onto the rail in the same orientation, re-engaging the release, and verifying door balance, travel limits, force settings, and photoelectric safety sensors per Genie instructions. Use this OEM Genie carriage assembly as a direct replacement part for maintenance or repair on applicable Genie garage door openers in residential applications.
