5" snaffle mouthpiece with a 1 1/8” long copper roller center & 8 1/2" loose cheeks. The Billy Allen mouthpiece is named for the legendary horseman. A roller covers the snaffle joint to stiffen the mouthpiece while still allowing some flexibility. The roller also acts as a pacifier that encourages salivation. This is an excellent bit for progressing your horse from the snaffle to the solid mouthpiece. A great, perfectly balanced show bit, constructed of polished stainless steel. Comes with connector chain(slightly rusty).
