The MB 29 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. The port itself is 1 ½" high, offering room for the horse’s tongue to pass under the bit. The flat plate above the port is 1 ¼" high and ¾" wide and tilts back rather than sitting straight up. When the reins are engaged, the mouthpiece collapses and applies two points of pressure on the tongue while the flat plate tips forward and applies pressure to the palate. The pressure on the palate is distributed across the surface of the plate. Sweet Iron mouthpiece oxidizes and encourages salivation.

Notes: The MB 29 is not designed for use by the casual rider. Its use requires a very experienced rider with excellent hand control and a horse that is very finished in his training who knows how to ride off seat and leg, as well as being very light on the rein aids. When palate pressure is applied properly, it causes the horse to drop his head but because the palate is so sensitive, that type of pressure needs to be used with great restraint. For the same tongue relief but with milder palate pressure, see the MB 27PB HP. For a solid version offering more tongue relief with palate pressure, see the MB 13C.
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.
