Used in the production of training and martingale collars, their unique make allows for the collar to partially tighten without the full tightening of a regular choke collar. When the half check chains are made into a collar, two of the rings have the collar sewn onto them and the third ring is used to attach the dog's leash when training. It also is useful as a martingale-like collar preventing your dog from backing out of its collar. Half check webbing collars on your dog are similar to using a choke chain, but quite a bit more comfortable for your dog because of the softer fabrics on their neck verses a full metal chain. With half check collars, the classic buckle is replaced by a chain and the collar is put on by pulling it over the dog's head. Half check chains, martingales, and training collars should not be used on a dog that is tied up. This is not an acceptable tethering application. Chains, D-rings, buckle, triglides etc. are sized by the webbing or straps they are meant to be used with. These chains are made to be used with 1/2 inch applications. Measurements of this product are: O-Ring: 1/2 Inch inside ring, 3/4 Inch outside ring, Chain: 3.17 Inch (from O-Ring to O-Ring with chain doubled).
