Keep the color of your trailer hook fly-tying wire consistent with the body of your fly. Stiff enough to prevent fouling, Senyo's Intruder Trailer Wire will become your go-to wire when tying any articulated fly. In black only.

Made in USA.

Sizes: small, large; 4 yards per pack. For hook sizes 6 and smaller, use small (18-lb. test); for sizes 6 and larger, use large (50-lb. test).
