I had just bought a new double-wide garage door, and looked at the rollers that came with it - looks like junk to me. I searched and found these, so as the installation happened, these rollers are in from the very start. Why wait a year or two and then replace the originals? Looking forward to a long smooth life from these!
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.
