INNOVATIVE GATE HINGE TENSION VARIABLE SYSTEM Safetech self-closing gate hinges are the only gate hinges on the market to feature our patented tension adjustment system. Once the gate hinge is in place, adjustments are made with just one handy allen key, which we provide. By simply turning the key clockwise, you can increase the tension of the self-closing gate hinge. As the tension changes, the system makes a clicking sound that lets you monitor just how much you’ve adjusted the gate hinge. The tension variable system makes Safetech Gate Hinges easy to install, so you can get the job finished in record time. DURABILITY THAT YOU CAN STAND BEHIND Not only are Safetech Gate Hinges the easiest gate hinges to install and adjust, but they’re also the most well made on the market. The general duty gate hinges are crafted from fiber-reinforced polymer and engineered for bind-free operation. The UV-stabilized gate hinges will not fade in the sun, and the rustproof design ensures their longevity.
