This is the Forward-tilted version of MB06. ¾ inch port angled forward 45o allowing Independent Side Movement. Acts on the lips and bars; and on tongue with a strong rein. It's suitable for a horse wanting to be polite but who can still spook or need refocussing. The 36 gives tongue relief when off or on very light contact, but does act on tongue with stronger contact. It works well for horses with limited room for port (often Mountain & Moorland; Arabs; Hacks).
