6 inch Cheeks, 5 inch Mouth. 3/8 inch Twisted Sweet Iron Dog Bone Snaffle. The slight gag design makes this lifter less intimidating and more accepting to many horses than the solid lifter. The three piece mouth offers additional leverage to the corners of the mouth providing a light responsive feel, while offering the rider the ability to reframe and rebalance a horse that has the tendency to lean on the bridle or drop his shoulder in turns or lead transitions.
