Myler Stainless Steel 7" Flat Shank, MB 29 Correctional Cathedral Port, Level 2-3
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.
