The medium port is a popular all around bit that has great application from the ranch to the show pen. The wide port base offers some tongue relief while the port applies gentle pressure to the palate. The shanks are 6 1/4" stainless steel and the mouth is a 5" medium port made from stainless steel with a copper roller that calms the nervous horse while keeping the mouth wet and responsive. 

Shanks: 6-1/4" Stainless steel
