The MB 27 is a traditional correctional mouthpiece, which has a ported mouthpiece that collapses on to the outer lip and bars, and rotates on to the tongue. This mouthpiece has a 2" port and is identical to the MB 27PB HP, except that it does not have Independent Side Movement. Sweet iron mouthpiece oxidizes and encourages salivation.
NO Independent Side Movement
Sweet Iron Mouthpiece
Notes: For the same mouthpiece with a lower port, see the MB 27LP. For the same height port but with Independent Side Movement, see the MB 27PB HP. For the same mouthpiece with Independent Side Movement™ but a lower port, see the MB 27PB.
The 7" Flat Shank is stainless steel and curved slightly back towards the horse, with a flat-top purchase and a rein ring. The mouthpiece has a fixed attachment. The Flat Shank has the patented Independent Swivel Cheek, where the purchase, mouthpiece and shank all move independently of each other. The purchase is slightly angled away from the cheek to avoid rubbing. It has an indirect (curb) rein action designed to be used with a curb strap which attaches to the purchase. The flat shank uses the combination of the fixed cheek and fixed rein to apply pressure to the mouth, chin and poll.
