What is the purpose of the keeper from the noseband to the throatlatch?
The ‘Connector Strap’ enables a lead rope or rein to be attached for leading, lungeing or groundwork. It goes back to the throatlatch to share the pressure between the noseband and transfer some to the poll, like a halter. It can be removed if you wish, but you never know when you may have to lead your horse with the bridle on. It works better to lead from the ring on the connector strap, than while the reins are attached to the chinstrap which would put conflicting pressure under the chin (that indicates stop!).
