Because of the additional sealing needed with vacuum systems, simply hand tightening the wing nuts may not be sufficient. The unique speed studs allow a quick, easy removal with a 1/2" socket. The lightweight, aluminum body is clear anodized for a long lasting finish. 1/4"-20x1-1/2" set screws and a 4 3/8" aluminum body are supplied. Set screws may be secured to the head or to the aluminum body. Two per kit.
