This was just what I needed to open a large overhead door in my pole barn. It fit perfectly and it works great. No more straining my back trying to heave the big door open!!
Ordered a gear kit to fix my garage opener, as the top sprocket had broken off. The item shipped quickly and was packaged well. Installation instructions were informative but I did not end up following them very closely. The part itself looked to be of OEM quality, if not better, and is holding up well so far (2 weeks after the install).
