FAQ

This belt is used on various Genie garage door openers that use a 5-piece tube-style rail for a 7-foot-high garage door. Reported compatible model families and models include Genie 1035, 2035, 2036, 2055, 3035, 3053, 3055, 7035, 7055, 7155, 1055, 1155, 3155D, and some SilentMax 550 and SilentMax 750 units. Because Genie used this belt across multiple openers, it is best to confirm your opener model number and rail style before ordering.
The main part number is 39354R.S. A commonly listed assembly reference is 05-39354R.S. Match your existing belt label, your opener model number, and the 7-foot rail configuration when verifying fit.
Common signs include a visibly frayed, cracked, stretched, or broken belt, the motor running without moving the door properly, jerky travel, belt slippage, or unusual rattling/slapping noises from the rail. On belt-drive systems, a worn belt can also cause inconsistent door movement or loss of travel limits if the belt has stretched significantly.
Yes. This belt assembly is intended for Genie belt-drive opener setups configured for a 7-foot garage door. Garage door opener rails and belts are door-height specific, so a belt for a 7-foot door should not be assumed to fit 8-foot or taller door setups.
Replacing the belt is usually a moderate repair. On most Genie belt-drive units, expect about 45 to 90 minutes depending on access and whether the rail must be partially disassembled. Typical tools include a ladder, socket set or nut drivers, wrenches, and screwdrivers. You will usually need to relieve belt tension, separate part of the rail or carriage assembly, route the new belt correctly, and then retension and test the opener.
Before installation, disconnect power to the opener and inspect the rail, carriage, pulley areas, belt path, and tensioning hardware for wear or damage. Also check that the door itself is balanced and moves smoothly by hand, because a heavy or binding door can overload the opener and shorten belt life. After installation, verify belt tension and run a full open/close test to confirm smooth travel and proper limit settings.
