Mackey Equisential Anti-Grazing Reins have been specially designed to stop your horse grazing. Featuring nickle plate fittings and made from 1'' soft nylon webbing. This clever gadget works by firstly attaching the reins to the girth and then looping them back to the bridle via the headpiece. They then clip onto the bit and the final adjustment of the roko buckles prevents the horses reaching the grass. Comes in a black colour and in one size only.
