ReinsmanDeveloped by Martha Josey7 Inch Cheeks5 1/2 Inch MouthCopper Wrap Dog Bone0119-6000 Restricted gag action allows for quicker signaling. 3 piece mouth with dog bone offers additional leverage to the corners of the mouth providing a responsive feel. This is a great choice for horses that need help picking up their shoulder. This shorter shank bit gives a moderate amount of Whoa. This 3pc twisted wire mouth with the copper dogbone keeps the horses attention without being too severe. The round ring is your headstall ring. The tear drop ring will be the rein ring. This keeps your reins in a at attention position for faster response. When fitted properly, the mouth should be sitting at the lowest position on the cheek when at rest. This allows the mouth to float upwards once pressure is applied to the rein. The curb chain should be started with a two finger spacing between the chain and horses jaw. Tightening the curb beyond this point will increase the leverage giving you more lift and rate. You can check for correct curb chain tightness by pulling on the rein. If the cheeks do not rotate beyond a 45 degree angle the curb is at its proper beginning tightness.
