The Genie 26012D.S Straight Door Arm is a genuine OEM replacement part for Genie garage door openers, designed to link the opener’s trolley to the curved door arm on a sectional overhead door. This rigid arm restores proper movement when the original component is bent, worn, or damaged, helping ensure smooth opening and closing, correct door alignment, and reliable travel. It is used in two-piece arm setups common on many Genie residential chain and belt drive units, serving as the straight section that connects the carriage to the door-side arm via standard pins or fasteners.
For compatibility, match part number 26012D.S to the parts list in your specific Genie opener manual or on the unit’s parts label, as models vary. Installation typically involves disconnecting power, placing the door in the down position, connecting the straight arm to the trolley and curved arm, and then verifying travel and force settings per Genie’s instructions; you may need to recheck or reset open/close limits after replacement. Use only on properly balanced doors and follow all safety precautions. This replacement arm is a practical solution for maintenance or repair on many Genie garage door opener systems where a two-piece door arm configuration is specified.
