The direct modern replacement and upgrade for the classic legacy LiftMaster 8500 wall-mount jackshaft garage door opener is the LiftMaster 8500W. The 8500W retains the same space-saving wall-mount direct-drive design that attaches to the torsion bar but adds built-in Wi-Fi and MyQ technology, eliminating the need for an external internet gateway accessory while including an automatic deadbolt lock. Verification: Check the product model label on the side of the motor housing to confirm the 8500W designation.
