The LiftMaster 041A2770-17 Installation Hardware Bag is a genuine OEM replacement kit designed for select LiftMaster and Chamberlain garage door openers. It supplies the factory-original fasteners and connection components needed to securely mount the opener and properly attach the door arm and related hardware during installation or service. Ideal for replacing missing or worn parts, this installation hardware bag helps restore a reliable, code-compliant setup without guesswork, supporting smooth operation in typical residential applications.
As a model-specific LiftMaster replacement part, compatibility varies by opener series; verify fitment by checking your owner’s manual or the parts diagram for your exact model number to confirm 041A2770-17 is specified. For best results, follow the manufacturer’s installation instructions, apply recommended torque to fasteners, and ensure the door is balanced before operation. Always disconnect power before service, have springs and counterbalance systems adjusted by a qualified technician, and complete all required safety checks, including setting travel and force limits and testing photo-eyes and auto-reverse per UL 325. This OEM installation hardware bag is a practical choice for repairs, upgrades, or completing an opener install with authentic LiftMaster components.
