The Herm Sprenger Curb Chain Guard is designed to sit between the curb chain and the horse’s chin groove, providing a soft cushioning layer that helps protect the sensitive lower jaw. It distributes pressure more evenly, reduces rubbing and pinching, and improves overall comfort when using curb bits or Weymouth setups. Made from durable black rubber, it is lightweight, easy to fit, and suitable for use with most curb chains.
