Tennis Arms are easy to install by slipping 12-inch tall fitter over pole or tenon, then fastened with 3/16″ diameter steel bolts. Arms are designed with a standard 3Â° tilt and have a very low EPA at a maximum arm length of 5′ from pole (including arm extensions for U-Arm and H-Arm). All arms are finished with a 5 millimeter powder coat to match luminaires. Tennis fixtures come with standard length wire of 6 feet for fast connection. Wires are protected from outside elements with tight-fitting black plastic snap-in end caps.
