The LiftMaster 41A4353-1 Header Bracket is an original equipment replacement bracket used to anchor the front end of a garage door opener rail to the wall header above the door. Installed on the centerline above the door, this bracket provides the secure pivot point that connects the opener’s rail to the structure, allowing the operator to open and close the door smoothly and reliably. It’s a common service part for LiftMaster professional operators and many Chamberlain and Craftsman openers manufactured by The Chamberlain Group that specify 41A4353-1 in their parts lists or installation manuals.
This header mounting bracket is intended for residential garage door opener systems and is typically used on chain-drive and belt-drive units that utilize a T-rail or square rail front connection. For proper operation and safety, install the bracket at the height and location indicated in your opener’s manual, anchoring it into solid framing on the header—not drywall—using the hardware and method specified by the manufacturer. Always disconnect power and follow UL 325 and manufacturer safety instructions during installation. To confirm fit, match the part number 41A4353-1 (also referenced by some sources as 041A4353-1 or 41A4353-1A) with your opener’s documentation; compatibility varies by model and revision.
