Bleacher enclosures increase safety by preventing unwanted traffic and accidents from occurring underneath the bleachers. Enclosures also improve the appearance of your bleachers and the entire facility. Take it a step further and add digitally printed logos and lettering. Bleacher enclosures are custom made to your specifications from Vinyl Coated Polyester, Polypropylene or 18 oz solid vinyl. Perimeter hems are reinforced with brass grommets.
