This unique letter attaches to the rails of any arena or equine fencing. The 8″ x 12″ plaque is UV treated and die-cut with rounded corners. Each plaque is silk screened with main and centerline letters, eliminating the chance of adhesives working loose. Channels are attached to the back, and available in different sizes. Rail letters are made to fit Premier Equestrian Arenas but will accommodate any fencing or other types of arenas.
