Fastway SHIN GUARD provides a cushion between your shin and the sharp edges of your ball mount. Installation is fast and easy. Protect your shins from a painful bump. Simply slide the injection molded rubber SHIN GUARD down over the top of the ball and stretch the bottom down around the nut. It fits both 2-5/16” and 2” hitch balls and on ball mounts up to 2-1/2” wide. It comes with an adjustable tether loop to keep your trailer wiring harness up off the ground while in motion.
