Wooden gates eventually sag, due to gravity, sometimes within a few months of installation. This gate sag will prevent the gate from closing. The Gate Glide™ is the easy way to prevent the predictable gate sag. Gate Glide™stops the sagging force of gravity on the closed gate, by transferring it to the latch post. It holds the closed gate in straight, aligned position. Gate Glide comes with easy to follow directions. The faces of each block slide against each other as the gate is closed. Each face has matching compound curves which engage each other as the gate swings closed. These curved surfaces lift and spread the gate back into alignment smoothly as the gate is closed holding the gate in its original straight and square position. The Gate Glide is made of heavy duty weather resistant material and can have a left or right mount. Click here to learn more.
