Not much to add other than these hinges fit my door perfectly. I replaced the number 2, 3, and 4 hinges. Be sure to look at your door and get the correct hinge(s) as each one is a different height to account for the track position and a snug fit when closed. I also ordered new rollers and replaced those while I was at it. With the new belt driven door opener, new hinges, and new rollers, the door is amazingly quiet during operation.
