Just about everyone who has a trailer hitch installed on their vehicle has screamed in agony after accidentally striking their shin or kneecap on the ball or receiver. A simple remedy involves the installation of the ShinShield. This protective device is made from a special polymer compound that the manufacturer claims will remain soft from -40 F to 150 F. ShinShield installs between the ball and most standard 2.5-inch (class 5) receivers that are rated for up to 17,500 pounds of gross trailer weight and 1,700 pounds of tongue weight. ShinShield sells for $20, or $25 if you want one that displays your favorite sport team’s logo. Order at www.hitchsolutions.net.
