Preformed Line Products TS-2103 Tangent Supports. Conductor type 2 #12 CW (or .083 Steel), Color code Yellow. Standard Loop and Elongated Loop Tangent Supports are intended to protect and separate one-pair aerial wires on a common drive hook. They accomplish this in the safest, easiest way possible: just wrap them on and hang them up. Because they wrap on in seconds without tools, they keep installation expense down and provide long, trouble-free service at the lowest possible cost.
