The MB 06 is a Myler alternative to the traditional mullen, but it has a wide, low port that allows the tongue to pass comfortably underneath. The port measures ¾" high, just enough to allow the horse's tongue to rise slightly and swallow, but not high enough for palate pressure. When the reins are engaged, the 06 applies pressure mainly to the bars and lips.

 

 

The hooks make this a much more versatile version of the thimble without hooks. Attaching the headpiece to the top hook keeps the bit in the right position instead of letting it slide around the cheeks of the bridle. Attaching the reins to the rein hooks allows the rider to lift the cheek and use the independent lateral movement ™ of the mouthpiece. Using hooks does not add leverage but allows the rider to switch from direct to indirect rein action without changing bits. Adding a curb strap (using a Myler curb strap kit) integrates curb pressure. Curb pressure is recommended for worn mouthpieces.
