One of my customers put up a fence. I told them to make sure that the gate opening is at least 60" wide. Well, the opening is, but the gate it self opens back on the post, only opening 90 degrees so I can't quite fit. I have hinges on my gate that have an L to the hinge and lets it open all the way back on the fence. It basically puts the pins at the back of the post and one leg of the L rests on the post and the other leg attaches to the gate. Where do I find these? I've been everywhere.
