With any towing setup， there is always the need for a few additional items. Though your trailer hitch and ball mount may be tough enough to haul that heavy load， they cannot properly tow without a few supporting players. Towing accessories are a practical addition to your rig that add the finishing touches and take your towing experience to a whole new level. With the right accessories， the difference is a little like cruising the Grand Canyon in a deluxe RV as opposed to camping out in grandma's backyard. For protecting your trailer ball when not in use， the CURT rubber trailer ball cover is a perfect fit. This cover is designed to fit a 1-7/8" or 2" diameter trailer ball (trailer ball and ball mount not included). You never know what obstacles the road before you might bring.
