The Big Ring Gag is made with stainless steel 4-1/2" rings and a sweet iron mouth. The Big Ring Gag is stronger than the usual Loose Ring and Eggbutt as the ropes going through the rings create leverage which will exert more pressure through the mouthpiece whilst at the same time introducing more poll pressure.
The Spinner sits on top of the horses tongue and prevents the horse putting its tongue over the bit.
The mouth piece is made from blue sweet iron, because it:
oxidizes easily
encourages salivation
helps bit acceptance
is warm and sweet
Please note the blue will fade with use.
