The Liftmaster 29B130 Belt Connector is a highly specialized Replacement Component and an essential piece of hardware for repairing or resizing legacy belt-drive Access Control systems. As a genuine OEM Gate Part, this belt clip connector kit is designed specifically to work in tandem with its counterpart (the 29B129) to create a secure, factory-grade splice. When a professional installer encounters an older garage door opener that requires a custom-shortened belt to accommodate structural beams or low-clearance headers, the 29B130 provides the necessary mechanical grip to rejoin the belt ends without sacrificing the smooth, whisper-quiet operation that belt-drive units are known for.
For technicians and end-users, this component is the missing link that prevents the costly requirement of ordering an entirely new custom rail and belt assembly. By securely locking the rubber or polyurethane teeth in place, it ensures that motor torque is efficiently transferred to the trolley, allowing legacy operators to continue functioning safely and reliably in residential environments.
Key Features & Benefits
• Two-Part Splice System: Engineered to interlock perfectly with the 29B129 connector plate, providing a vice-like grip on the belt ends that will not slip under heavy motor torque.
• Precision OEM Tooth Grooving: The internal profile of the clip matches the exact pitch and depth of older Chamberlain Group drive belts, ensuring perfect timing and preventing mechanical slipping during travel.
• Heavy-Duty Stamped Construction: Built to withstand the immense and constant pulling forces of daily garage door operation without bending, warping, or stretching over time.
• Low-Profile Splice Design: Once fully assembled and crimped, the connector is flat enough to easily navigate the primary drive sprocket and idler pulley without snagging or causing loud clicking noises.
• Cost-Effective System Repair: Allows field technicians to easily shorten an existing belt to fit modified rails or complex garage depths without replacing the entire drive assembly.
Compatibility Guide
Following strict manufacturer engineering protocols, the Liftmaster 29B130 Belt Connector is specifically designed for legacy belt-drive garage door openers manufactured by the Chamberlain Group.
• Compatible Brands: LiftMaster, Chamberlain, and Sears Craftsman.
• Supported Models: Specifically engineered for the 1270, 1280, and 1280R series belt-drive garage door openers.
• Production Era: Required for splicing older style belts on units manufactured between 1995 and 2007.
• Strict Integration Requirement: This is Part 2 of 2. It absolutely must be used in conjunction with the 29B129 belt connector piece to form a complete splice.

Frequently Asked Questions
Q1: Can I use just the 29B130 to fix my broken belt?
A1: No. The 29B130 is only one half of the required hardware. You must also have the 29B129 connector plate. The two pieces sandwich the ends of the belt together, and the tabs on the 29B130 are bent over to lock the assembly.
Q2: Will this connector work on my new LiftMaster 8550W belt drive?
A2: No. Modern LiftMaster belt-drive units use a different continuous-loop, steel-reinforced belt design and utilize different tensioner hardware (such as the 109B33 clip). The 29B130 is strictly for legacy operators built from 1995 to 2007.
Q3: How do I know if I need this splicing kit?
A3: This kit is primarily needed if you are installing an older 1270/1280 unit in a garage where the rail must be cut down (shortened) to fit around a beam, plumbing, or a shallow wall. After cutting the rail and the belt, this kit is used to reconnect the belt to the proper length.
Q4: Do I need a special crimping tool to install this connector?
A4: No proprietary OEM tools are required. Once the belt ends are seated between the 29B130 and the 29B129, a pair of standard heavy-duty channel-lock pliers or vice grips can be used to bend the metal tabs inward, permanently securing the splice.
Q5: Should I apply any glue or epoxy to the belt before clamping it with the 29B130?
A5: No. Belt splicing relies entirely on the mechanical grip of the metal teeth matching the rubber grooves of the belt. Introducing adhesives or epoxies can cause the belt material to degrade, harden, and eventually snap under tension. Assemble the connection completely dry.
