The Blocker Knotless Tie Ring prevents injury to you or your horse. When a solid-tied horse spooks or falls, it can panic - then something breaks or the horse injures itself (or both). Quick-release knots and panic snaps put you in danger as you try to reach them. The Blocker Tie Ring works WITH the horse. When the horse pulls hard on the lead, some of the rope slips through the tie ring - releasing pressure AND the source of panic. If the horse falls in a trailer, it can pull enough slack to get itself back up.
