The Genie 27080B Chain Sprocket Bracket is an OEM replacement component for select Genie chain-drive garage door openers. This bracket secures and positions the chain drive sprocket at the opener head, keeping the drive chain aligned so the door travels smoothly and reliably. It is used when repairing a bent, worn, or damaged sprocket support on compatible Genie models and helps resolve symptoms such as chain derailment, excessive noise, or erratic travel. Refer to your opener’s parts diagram or service manual to confirm that part number 27080B is specified for your unit, as this is not a universal component and compatibility varies by model family and production run.
Installation typically involves disconnecting power to the opener, releasing the door from the trolley, supporting the rail, removing the opener cover, and transferring the sprocket assembly to the new bracket before reassembling and re-tensioning the chain per the manufacturer’s specifications. For safety, always disconnect power and secure the door in the down position before service; if you are not familiar with opener repair, consult a qualified technician. The 27080B Chain Sprocket Bracket is designed for residential and light commercial Genie chain-drive applications that list this exact part number, making it a dependable, direct-fit replacement part for maintaining proper chain alignment and drive performance.
