The Cart Clamp is an accessory rail that quickly and easily mounts to the right or left roof support of most golf carts without tools (even those with windshields). Various storage accessories slide into the grooves in the rail and lock securely. The Cart Clamp allows you to keep all of your paraphernalia, golf glove, golf GPS, wallet, cell phone, cigar, sunglasses, a sandwich or snack, within easy reach when you are riding in a golf cart. Once you initially set up the Cart Clamp, you can leave it set up and install it on any golf cart in 30 seconds without tools. This allows the average golfer that just goes out to a public course and rents a golf cart to have his own custom golf cart right in his bag.
