One slick little clamp, our chrome plated stainless steel P-Clamp has many uses. It works great for mounting Silver Bullets, Hornet Deer Alerts or other items to frame tubes or engine guards. Its hinged design makes installation easy. Mounting is very secure because our clamp is secured to the tubing by both a flat head screw and the fastener used to attach the accessory. The clamp has a 5/16-inch mounting hole. P/N 4017 fits both 39mm and 41mm fork tubes.
