The Trust Equestrian Inno Sense Ported 2.5 Ring Eggbutt Gag combines a ported mouthpiece with 2.5 ring sides.
The top ring is attached to the cheekpieces to apply poll pressure, resulting in the horse's head lowering, while the half-ring gives leverage, causing a head raising action. When these actions are combined, it results in a gag action. The 2.5 ring, sometimes known as a Universal, is the mildest version of a ring gag as the half-ring softens the leverage on the mouthpiece. Meanwhile, the eggbutt sides prevent pinching while giving a more direct action than a loose ring.
The synthetic ported mouthpiece is ergonomically shaped to allow space for the horse's tongue, and is available in Medium or Hard densities.
Available in 12.5cm (approx 5in), 13.5cm (approx 5 1/4in) or 14.5cm (5 3/4in).
