For gates with flat mounting surfaces and a maximum thickness 2", an alternate to using U-bolts would be: 5/16-18 x 3" hex head bolt with associated flat washers, lock washers and hex head nuts (4). For chain link fences or other types with circular rails, it is best to attach a vertical support panel connecting the top rail to the bottom rail. The gate bracket can then be mounted to this vertical panel using the same bolts, washers and nuts as mentioned above.
