The Genie 36773T Carriage Assembly is an OEM replacement trolley (also called a traveler) for select Genie garage door openers equipped with rails configured for 10, 12, and 14-foot door applications. This component rides along the opener rail and connects to the door arm, transferring motion from the drive system to raise and lower a residential sectional garage door. It includes the interface for the manual emergency release so the door can be disconnected and operated by hand when needed. Replacing a worn or broken carriage restores smooth, reliable travel and proper engagement with the opener’s drive system.
This Genie carriage assembly is intended for use only on compatible Genie opener models that specifically list part number 36773T in their parts diagrams or service documentation. Because Genie produced multiple carriage designs across chain, belt, and screw-driven systems, verify the exact part number against your opener’s model and rail type before ordering. Typical installation involves disconnecting power, pulling the emergency release, detaching the door arm, sliding the old trolley off the rail, installing the new carriage in the correct orientation, reattaching the arm, and then checking or resetting travel/limit adjustments. After installation, test safety reversal and photoelectric sensors per the manufacturer’s instructions. No remote programming is generally required unless limits or force settings are adjusted.
