This is a flexible, nathe-style, mullen mouth gag curb.
The Gag Curb uses the concept of a rope gag but instead of applying poll pressure, it is used to apply curb pressure from the second/bottom rein. Although poll pressure is not totally removed as there is a similar action to the Ring or Drop Cheek on the bit/top rein. It is supplied with curb strap.
It is great for horses with a sensitive mouth but when you still need a bit that delivers control.
