Complete pen consists of 11 panels, each 2100mm high x 2400mm wide, plus a gate section making up into a ring 9m (30ft) in diameter. Mesh size 75 x 75mm (3" x 3"). NOT suitable for foals or ponies. Safety has been a major consideration in the design, each panel and the gate sections are made up of heavy gauge box section steel with welded mesh infill and panels incorporating a centre bar to avoid distortion when they are moved about from place to place, or removed or replaced. The unique hinge which allows the panels to be easily demounted and moved when required, also allows additional panels to be incorporated to make a larger ring if required. Panels can also be removed to make a smaller enclosure for a foal creep or protection for the injured horse. Remember only the 50mm square (2" )small mesh pens are suitable for foals, this one is not.
