These ratchet harnesses are so good I bought two of them back to back. I believe they are also called auto-lock belts. They're really handy as they don't have any pins or holes, just pop them in when they click and that's it. Detaching the strap is as easy as pressing a button and a finger, no kidding. Ever since I got my first ratchet strap a few years ago, there has been no turning back. I highly recommend everyone to try these out and ditch the usual pin and hole belt. These belts are made of good genuine leather and the metal parts are made of high quality metal alloy. just love her
