The Gate Latch is made of an nylon molded part that will not corrode and is available in gray or black. This latch prevents rattling and the gate from swinging inward. This gate latch can operate on right or left hinged gates and can fit 1”,1-1/8” or 1/14” square tubing. It is very easy to install as all parts can be installed on the gate with the three #10 screws.
