Weaver Leather Gag Bit, 5" Copper Wire Wrapped Mouth with Center Ring, This stainless steel gag bit has a 5" copper wire wrapped mouth with center ring, 6-1/2" cheeks and a satin finish. Depending on the degree of slide on the gag, these bits aid in lifting the shoulders, allow more flex for turning and provide more control at a higher rate of speed, making them popular for barrel racing and other speed events. These bits should be used with a loose chain curb. Please note: Horses should never wear a bit when tied.
