Patented hook and loop design 'breaks' apart under a panic load, but the tie isn't really broken at all! The short end of the tie stays with the horse and the remaining long section is still connected to the wall or trailer. Just catch your horse and put the tie back together! Fantastic idea for stables and it doesn't have the 'snap back' danger of a stretchy tie. Features a panic snap at one end and solid brass trigger snap at the other. A lot more attractive than baler twine everywhere- A great product that will pay for itself!
