Surfstrand 1x7 is made of corrosion resistant- spring temper stainless steel. Compared to our competitors old style 1x3 construction- Surfstrands 1x7 construction offers higher break strength and more realistic action. The wire is specially stranded to deliver superior kink resistance- and the 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.
