The MB04 is similar to the MB02 in that it will rotate on the tongue and apply tongue pressure, however, it has a small (¼") port that introduces some tongue relief to the horse. The port allows the horse to swallow and move his tongue when he is moving forward and relaxed, which acts as a release or reward. The mouthpiece is curved, and it wraps around the bars and lips instead of pinching.

*Stainless Steel Mouthpiece
*Curved mouthpiece does not pinch lips and bars
*Copper Inlay
*NOT Dressage Legal

Notes: The MB 04 provides an excellent transition from Level One to Level Two. It is suitable for a wide range of horses including green horses, experienced horses entering the Myler System, horses that have been ridden exclusively in a single-jointed mouthpiece, or horses that have not been ridden for a while needing re-schooling.

The dee with hooks is a stainless steel "D" shaped ring with fixed attachment of the mouthpiece, as well as slots (“hooks”) at the top and bottom of the ring for bridle and rein attachment. The small loop behind the top slot accommodates a curb strap (attach with two curb hooks). Both the top bridle slot and bottom rein slot on the standard and medium dee will fit standard ⅝" bridle leather. The slots on the pony dee will fit ¾" bridle leather.

The hooks make this a much more versatile version of the dee without hooks. Attaching the headstall to the top hook holds the bit in the correct position instead of allowing it to slide around the bridle cheek pieces. Attaching the reins to the rein hooks allow the rider to lift the cheek and use the Independent Side Movement™ of the mouthpiece. Using the hooks does not add leverage but allows the rider to transition from a direct rein action to indirect action without changing the bit. Adding a curb strap (using a Myler curb strap kit) incorporates curb pressure. Curb pressure is recommended for ported mouthpieces.
