Review on Garage Hinge HEAVY Galvanized Finish by Elvis Kohl

My old hinge was about 1/4 inch smaller but all the screws matched and the GDO opens/closes fine. I bought this and did exactly what I needed. I used a percussion gun to remove the old bolts and screw in all the bolts with a new loop. I then hand tightened the last few turns to avoid removal. Run the GDO a few times and double check that all screws are tight. After that, I would suggest checking about once a year.
