The Havana Leather Halter 1" Replacement Crown piece from Walsh allows you to replace the top of your horse's halter if it breaks without replacing the whole halter. The leather crown piece on a halter is designed to break in emergencies, keeping your horse from being dangerously trapped. Keep a replacement crown piece on hand for your halter so that it can be quickly replaced and used immediately following a break. Crown pieces are sized to match your halter and are offered in sizes 6 (Cob), 7 (Horse), or 8 (Oversized).
