The LiftMaster 41A6264 Screw Drive Rail Assembly is a genuine OEM replacement rail for select LiftMaster residential screw-drive garage door openers. Designed for standard 7 ft (2.1 m) door applications, this complete rail assembly restores the drive path between the opener head and trolley, helping ensure smooth, reliable opening and closing. It is intended only for LiftMaster models that specifically list 41A6264 in their parts diagrams; it is not interchangeable with chain- or belt-drive rails and should be matched to the opener’s model number and parts list before ordering.
As a factory rail assembly, 41A6264 is built to meet LiftMaster specifications for alignment and travel of screw-drive systems. Typical use includes replacing a bent, noisy, or worn rail to correct carriage travel issues and improve overall operation. Installation should follow the opener’s original LiftMaster manual: disconnect power, secure and balance the door, remove the old rail, install and align the new assembly, then set and test travel limits and safety reversal. After replacement, verify proper operation of photoelectric sensors and perform a full door balance and force check. For the best fit and performance, confirm compatibility by referencing the opener’s model label and official LiftMaster parts documentation for 41A6264.
