The item itself fits the 1797 with Powerforce Helix Turbo Winder. But after installation it didn't spin and also melted the belt so I bought a new belt and thought about it. it was, but then after I pulled it out. It's missing the ec-292 end cap which caused the brush to spin, cutting the inside and burning the other strap. Check them before you turn them on so this doesn't happen to other people.
