Bob Avila Square Port Roller Del Mar Bit
This mouthpiece is a port with a copper center roller, allowing tongue relief and enabling independent rein action. This bit provides lateral control of the poll. The copper roller keeps the horse's mouth moist. The cheeks are engraved aluminum which is light and comfortable. The port is fixed with the copper roller over it.
Port: 1 1/2"
NOTE: This bit will rust when exposed to moisture. This creates a sweet taste in the horse's mouth and promotes salivation.
