With a traditional strap-style hinge, the gate’s weight can loosen the wood grain around the screws, leading to sag. By contrast, the GForce Hinge has flanges that grab the top and bottom of the 2-by rail, and the gate’s weight compresses the wood grain, limiting sag. Fastening the hinge to the framing also means that the gate can be built in place, making it easy to achieve an exact fit. All Weather Fence, 850.916.0570, gforcehinge.com
