Closure Panels
Closure Panels are designed to use in place of skirting and prevent objects from falling through the space between the tiers. They are fabricated from plywood, have a polyvinyl surface and the edges are trimmed in rubber T-molding. Closure Panels enhance the overall appearance of your riser system while providing additional safety measures.
These two photos show the space between the two deck levels, which is eight inches, and how the space becomes totally closed with closure panels.
