The Boss Strap on the SS107 helps manage a few pain points of kayak fishing making your time on the water more efficient and more organized while keeping noise at a minimum. Featuring raised bosses on the underside and top side of the full rubber strap, the top side is great for aiding in staging and keeping your rod tips separated and ready to cast. The bosses on the underside of the strap help provide friction when storing the blade of your paddle keeping everything secure and quiet yet easily within reach. Included in this kit are four black nylon washers and four stainless steel screws. Made in the USA.
