The MB36 Myler Forward-Tilt Ported Barrel Hanging Cheek has a 19mm high (three quarters of an inch) port angled forward at 45 degrees allowing independent side movement. The bit acts on the lips and bars of the horses mouth; and also on the tongue when a stronger rein is used. The Myler MB36 gives tongue relief when off or on very light contact, but does act on the tongue when a stronger contact is applied. It works well for horses with low palate with limited room for a port, which is accommodated by the forward tilt that exerts pressure forwards and downwards onto the tongue as the riders rein pressure is increased instead of rotating from further back and upwards into the horses soft palate area.
