The Fort Worth Cribbing Collar is made with American Leather sourced from the world's finest tanneries. The leather is very durable allowing for less tightening of the collar compared to others. The unique design keeps the collar in place with a single strap, and hardware used is stainless steel. The collar will loosen when the horse drops its head to eat, so it is recommended to check the fit at the horse's normal cribbing position. The fit of the collar should be checked and adjusted over time to ensure the best results.
