We've all done it - gone around the back of the car, or 4WD and smashed our shins on the tow-ball. There's nothing worse and it hurts like heck. Thankfully with this new all-in-one tow-ball cover and shin protector, you can make it a thing of the past. Fitting most 50mm 1 7/8-inch tow-balls, this protector is made from durable and flexible rubber. It features non-slip teeth and a special groove to store your tow-ball cover while towing, so it doesn't get lost or stolen. This all-in-one unit will not only protect your shins, but also your clothes from any grease and grime on the tow-ball.
