The LiftMaster 41A4353 Header Bracket is an original equipment replacement part designed to secure the front end of a garage door opener rail to the header wall above the door. By anchoring the rail at the correct centerline, this bracket helps maintain proper alignment and smooth travel of the trolley, supporting reliable operation of compatible LiftMaster systems. It is typically used with residential chain-drive and belt-drive openers where a fixed attachment point at the header is required to stabilize the rail assembly.
This header bracket is used on many LiftMaster, Chamberlain, and Craftsman openers that specify part number 41A4353 in their parts lists. Installation generally involves fastening the bracket into structural framing at the door centerline and attaching the rail to the bracket with the proper pin and retainer as shown in the opener’s manual. For safety, disconnect power to the opener, support the rail during installation, and follow all instructions and torque requirements in the model-specific documentation. Always verify compatibility by checking your opener’s parts diagram or service manual for 41A4353 before ordering.
