Nice 5" Mouth training bit. Commonly used with 2 reins, one connected to the bottom ring for the curb action, one connected to the D for direct reining. As training progresses the D rein is removed. The D itself is helpful though as the horse can feel the slight pressure on the side of his mouth from the D when the curb rein is used. This property makes this a very popular bit for training horses to a full western bridle.
