When tying your horse, simply attach Equi-Ping to the metal ring on your stable wall or horse trailer, and then tie your horse's lead rope to it as you normally do. If your horse or pony panics and pulls back, the Equi-Ping is designed to "ping" open when approx. 175 lbs of force has been reached to help avoid injury to the horse. Totally reusable! Effective between 20-25 times before it needs to be replaced in most circumstances. Nor more ugly baling twine hanging off your trailer. Consistent release unlike twine that breaks sometimes easily, sometimes too late. Great for cross ties also! *Now with a new security sleeve*
