TWO BRASS SNAPHOOKS THAT DONT RUST. This chain is to fit on the cross chain which should be across the back of the cab on your vehicle, whatever it is be it a 4 x 4, or ute, to which you can attach the dogs as they get on the deck of the vehicle, or in the back. It can be attached anywhere there is a suitable location to snap the snaphook onto, to hold the dog on whilst you play at Barry Crump and his mate, Shorty. Swivel in the middle to stop the tangling, and two swivel snaphooks, one on each end for easy connect and disconnect. Carry one in your pocket to tie up the dog or animal whilst you attend to the job, very handy. Overall length is approx. 20 inch. Both snaphooks have swivels on the bottom eye as well, so this setup wont twist like some other cheap twisted chains. Have a look at the photo, it tells it all.
