1 inch wide HeavyWeight Nylon is used for the design of this everyday leash. Comes hand stitched with an OG box stitch design. The Carabiner clip is crucial for not only everyday use but also agitation work. With a weight rating of 500kg (1,102 lbs) this is a crucial lifeline between you and your dog that is certain not to fail. In addition, the nylon itself has a 1,800lb weight rating, is water resistant and perfect for outdoor use. The Carabiner clip is less than 3 and a half inches long and extremely light making sure not to hinder the pressure used on prong collars that are essential for clear communication between you and your dog. This leash also has a self locking feature to ensure under no circumstances will it accidentally under the right pressure and angles come loose. Did you know that the standard clip hooks used on everyday leashes only have a weight rating of 86lbs? Neither did I. Being a working dog owner myself, this brought some discomfort to me everyday not knowing when my leash would fail me. Sure enough it did. First it was the spring getting locked and jammed and second it was the “spring clip” that fell off during agitation work and if my dog didn’t have a good recall, well... we would have been f******. This leash has been everyday tested, the nice handle at the end makes it easy to slip the carabiner clip through for easy attachment ties to railing, posts, or chairs for a quick and secure tie back. This also allows for you to convert it into a cross body hands free leash.Near the attachment point is a 1 inch Velcro strip hand sewn on that allows you to attach Velcro patches.
