The LiftMaster 29B130 Belt Connector is a genuine OEM replacement component for select LiftMaster belt‑drive garage door openers. It serves as the belt anchor/connector within the rail assembly, restoring the proper link between the drive belt and the moving hardware so the trolley can travel smoothly along the rail. Use this part when repairing a slipping, broken, or disconnected belt assembly on residential belt‑drive systems. Because LiftMaster components are shared across Chamberlain Group brands, this connector may also appear in parts diagrams for certain Chamberlain and Craftsman belt‑drive openers; always confirm by matching the 29B130 part number in your model’s manual or illustrated parts list.
Installation typically involves relieving belt tension at the turnbuckle, removing the worn connector, routing the belt through the trolley as specified by the manufacturer, securing the new connector, and then re‑tensioning and testing travel limits and force settings. For safety, disconnect power, keep the door fully supported, and follow the opener’s service instructions during setup. This OEM belt connector helps ensure reliable belt engagement and smooth, quiet operation after a belt replacement or routine maintenance, making it a practical, model‑specific replacement part for LiftMaster and compatible Chamberlain Group belt‑drive openers.
