Full Gag Hanger converts any bit into a gag bit, by simply sliding the Gag Hanger underneath the headstall then attach the other gag cheek. Once attached, simply pull the rope/ring through the cheekpiece on any D-ring, full cheek, etc and attach the rein to the ring. It can be used with just a single rein, or with one attached normally to the bit cheek and another attached to the gag ring.
