Match the color of your trailer hook or fly color scheme with Senyo's Intruder Trailer Hook Wire. Senyo has tested this wire, doubled over like you'd tie it on an intruder, at over 50lbs tensile strength. It is stiff enough to hold your hook in the right position without fowling. For hook sizes 6 or larger. Also is perfect for tying barracuda and shark leaders, and is especially good for tying articulated flies for any toothy critters. Each package contains 4 yards of material.
