Great to do business with. Excellent communications. I was expecting a cheap China knock off. Got Genuine OEM part! Fairly good instructions. One step omitted in the written instructions and the videos (NOT YOURS). There is one hole that MUST line up or you will NOT be able to install the "Chain Spreader". At this point in time, if you have installed the part, you'll have to go almost back to square 1. Make sure the hole in the plate lines up with the hole for the screw to anchor the Chain Spreader. Watch for avoiding a flip or twist in the chain. All installed and working well.
This kit made installing the springs easy. I bought a few parts at the hardware store because the person who attached the previous springs had rigged up something a bit non-traditional. I wanted the install to be easy, so I used what was already in place and replaced what was necessary (springs and pulleys).. I might buy another set just to have as back-up...
The product was exactly what I needed and fixed the opener. The only issue I had was the original piece had threaded holes and the new one did not. I had to run out and get a few nits and bolts, but all-in-all it was an easy and effective repair.
