The 47PB is a correctional mouthpiece, a ported mouthpiece that collapses on to the outer lip and bars, and rotates on to the tongue. The port is narrower than a Level 3 mouthpiece, but offers plenty of room for the horse’s tongue to pass under the bit. The angles of the port are rounded, so when the bit collapses and applies two points of pressure on the tongue, the pressure is mild. The port on this mouthpiece is 1 ⅞" high, so it will apply some palate pressure. Sweet Iron mouthpiece oxidizes and encourages salivation.
Independent Side Movement
Sweet Iron mouthpiece
Curved mouthpiece does not pinch lips or bars
Notes: A horse with a thicker tongue or lower palate will feel more palate pressure. This mouthpiece is the correctional version of the MB 43HP and is identical to the MB 47, but with the added benefit of Independent Side Movement. For increased tongue pressure and same palate pressure, see the MB 27PB or MB 27PB HP. For more tongue relief with same palate pressure, see the 43HP. For less tongue pressure and little to no palate pressure, see the MB 43LP or MB 43MP. For the same mouthpiece but without Independent Side Movement, see the MB 47.
The 5" HBT shank is stainless steel and slightly curved back, with a flat-top purchase and a rein ring. The mouthpiece has a fixed attachment. The HBT 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 HBT shank uses the combination of the fixed cheek and fixed rein to apply pressure to the mouth, chin and poll.
Degree of Leverage: Mild
Notes: The HBT is well suited to trail riding as the shorter shank makes grazing easier for the horse.
