The 439-2 is a speed flex leader designed for making cables installs easy. The silver-solder joint attaches to any 1/8" (3.2 mm) x .060" (1.5 mm) steel fish tape to provide a slim profile that fishes farther and faster. High-strength stainless steel cable is used for reliability and long life in the construction of the 439-2. It features beveled edges on the leader to reduce the possibility of hang-ups when pulling wire, and up to (6) #10 wires can be attached to the large pulling eye.
