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).
I purchase this part after reading that this is the replacement part for my Genie screw drive is not working and this is the likely culprit of the cause. The part was inexpensive and came quickly. Followed the YouTube video on how to disassemble my Genie and replace this part. It was exactly the part that I needed for replacement. Now my garage door is functioning again.
