I live in Northwest Florida (aka Hurricane Alley). I had a hurricane reinforced garage door installed a couple of years ago. I noticed they installed three rows of hinges. The door contains five rows of hinge mounting points. I bought my first set of these to add to the points that lacked hinges. These were much heavier duty they the OEM hinges. They fit perfectly so I went and ordered enough to replace the existing Number 1 hinges. The door is much more quiet when opening and I believe better suited to with stand Mother nature. Be aware they did not come with screws. Lowes had compatible ones for a reasonable price.
