Product Description
The Genie 27191A.S is a genuine OEM 10-tooth chain drive sprocket that mounts directly to the motor drive shaft inside the powerhead of compatible Genie chain drive garage door openers. The sprocket engages the chain on the T-rail, transmitting motor torque to open and close the door. It is engineered for chain drive systems using 7'6" and 8' channel T-rail configurations and is compatible with ProMax 700, PMX 1200, GPS 700 IC, GPS 1200 IC, PMX series IC/A and IC/B, IC250, IC250/B, Stealth 0700, and Stealth 0800-CC models. This sprocket is not interchangeable with belt drive or screw drive hardware. Replacing a worn or damaged sprocket with a genuine OEM part ensures the correct tooth profile, chain engagement, and drive performance.
