The Genie 26013D.S Curved Door Arm is a genuine OEM replacement component that connects your garage door opener’s trolley to the door via the door bracket, forming the curved half of the standard two-piece arm assembly (curved + straight). Designed for smooth, reliable lifting and lowering of sectional overhead garage doors, this part restores proper door travel geometry when the original arm is bent, worn, or damaged. It’s commonly used on residential Genie openers that specify 26013D.S in their parts list, including many chain-drive, belt-drive, and screw-drive units that use a two-piece door arm configuration.
Installation typically involves disconnecting power, securing the door, releasing the opener’s carriage, and attaching the curved arm between the door bracket and the straight arm per the opener’s manual. After replacement, you may need to re-adjust open/close limits and force settings, then test safety reversal and photo eyes to comply with UL 325 safety requirements. Compatibility varies by model, so confirm 26013D.S against your owner’s manual or parts diagram. This OEM Genie curved door arm is an ideal replacement part for maintaining dependable operation in residential sectional garage door applications.
