Surfstrand 1x7 is made of corrosion resistant, spring temper stainless steel. Compared to our competitor's 1x3 construction, Surfstrand's 1x7 construction offers higher break strength and more realistic action. The wire is specially stranded to deliver superior kink resistance, andthe high strength of stainless makes this an excellent wire for leaders, lures and trolling. Camouflaged Brown finish minimizes reflections and disappears beneath the water. Attach Surfstrand using crimping sleeves and crimping pliers or tie with a figure 8 knot.
