Flat Chain Curb Strap from Martin Saddery and Classic Equine
Flat Stainless Steel Chain Curb with chain hooks.
Curb straps are used for many reasons. They prevent pulling the ringed bits through the side of the horse’s mouth and help to stabilize the bit and keep it centered. For one-handed riding, they help to stabilize longer shanks and can add be adjusted to add more pressure for precision. They also help to protect the horse's mouth while roping by preventing the rope from getting between the shanks and catching one side, forcing one shank up and out.
