Genie Screw Drive Carriage | 36179R.S

The Genie screw drive carriage assembly with magnet has teeth inside it that connect to the screw inside the garage door opener rail. The carriage teeth gripping the screw allow for smooth operation of running the garage door up and down the rail. If the motor on your garage door opener is running and the screw drive is turning, but the garage door is not operating (you may even hear a grinding or chattering noise), then it is time to replace the screw drive carriage.

• Works with magnetic or mechanical style limit switches
