The Genie 36773R.S Carriage Assembly is a genuine replacement trolley for select Genie residential garage door openers configured for a 7-foot door. This carriage travels along the opener rail, engages the belt or chain to move the door, and connects to the door arm for smooth open/close operation. It is commonly used to restore reliable performance when the existing trolley is worn, slipping, or won’t engage. Designed for select Genie chain-drive and belt-drive systems with a 7' rail, it is not intended for screw-drive or wall-mount operators. Buyers often search for this part as a Genie trolley, garage door opener carriage, or 7' door carriage replacement, and it is associated with popular Genie residential families such as ReliaG, ChainLift, BeltDrive, and QuietLift (model-specific fit varies; verify by opener model and rail type).
Installation typically involves disconnecting power, pulling the emergency release to disengage the door, sliding the old carriage off the rail, installing the new carriage, re-engaging the opener, and testing operation. After replacement, limit and force settings may need to be checked and adjusted per the opener’s owner’s manual. For safety, ensure the door is balanced and the opener is powered down before service, and use only on compatible Genie 7' rail assemblies; taller doors or extension-rail configurations may require a different trolley. Refer to Genie documentation or the opener’s model label to confirm compatibility with part number 36773R.S.
