Cover Wooden Edges Cover wooden edges with sheet metal or heavy screen. Several stall manufacturers offer chew-guard edging. Don't use home dry wall edging - it's too flimsy and a horse can easily tear it to pieces, exposing dangerous sharp edges. Nails, although easier to use than screws, can creep out, and the projecting heads can catch a horse's mane and tail hair or cut him. Galvanized metal screen, or hardware cloth, can be used to protect round poles where angle edging won't work.
Some horses love to rub on the rough surface, though, resulting in patches of lost hair.
Be sure to fold under the sharp cut edges and use plenty of screws to fasten the seams to prevent injury to you or your horses. Make Wood Unpalatable Treat wood with an anti-chew substance.
