Works

I used this to secure loose ends behind knots at the ends of 1/2" poly rope. Poly rope being hard to get a good cinch, I used these after the knot to hold the ends down next to the line. They work great as a backup to the knot so as to make it more difficult for the knot to become untied. I bent the tabs over with pliers then hammered them tight. The stainless is great as most of the rope I used will be submerged in a fresh water lake.
