The FES Bit Western Swivel 7 Loose Flat Cheek is a fantastic tool for those looking to transition their horse from a traditional snaffle to a shank style bit. The lower port design is relatively mild and applies pressure directly to the bars, offering enhanced control. The loose cheeks prevent pinching in the corners of the horse's mouth, ensuring comfort for your horse. Made with flat stainless steel, this bit offers durability and longevity. With precise sizing - mouthpiece: 5", cheeks: 7", port: 1", and bit diameter: 3/8", you can ensure an optimal fit for your horse.
