This trail dee is designed for the well trained horse to comfortably carry all day long. The headstall ring aligns the mouthpiece at a pleasing angle in the horse's mouth and prevents downward rotation of the mouthpiece when rein pressure is applied.Comparable to an English Kimberwicke without the leverage element, this 3-Piece Sweet Iron Snaffle with Copper Roller is a great choice for the nervous or busy mouthed horse. The mix of sweet iron and copper promotes salivation and combined with the overall design, encourages relaxation of the jaw. Allow your horse to relax and enjoy the trail as much as you do! Copper is a soft metal, check for signs of wear before each use. | Reinsman Trail Dee 7/16" 3-Piece Smooth Sweet Iron Snaffle with Copper Roller Bit | Size 5"
