Stainless Steel 3 3/4" Dee with 2 Hooks, with Stainless Steel Mullen Triple Barrel (MB 32-3) Copper Inlay Mouth. About the mouthpiece: the 32-3 is the Myler alternative to a traditional mullen. It has three barrels which turn the mouthpiece from the typical solid bar of a mullen into a flexible bar which allows the horse to elevate his tongue and swallow more easily under the bit. When the reins are engaged, the 32-3 becomes a solid bar like a traditional mullen, but with an exaggerated curve. This curved bar rotates across the bars and lips down on to the tongue, applying pressure across the entire surface of the tongue. The flexibility of the 32-3 makes it very forgiving and comforting when relaxed, but offers the rider control when engaged. The pressure on the tongue is distributed across all three barrels, which also create the Independent Side Movement . Because the tongue pressure applied by the 32-3 is evenly distributed across the entire tongue, this mouthpiece is considered "stronger" than the 04. However, its flexibility makes it a forgiving mouthpiece that works well for horses who have suffered mouth trauma or damage, or horses that tend to go behind the bit. For a ported mullen style offering more tongue relief, see the 06 or 36. From The Level Best for Your Horse by Dale, Ron and Bob Myler. ©Toklat Originals, Inc.
