Attic Dek is the only storage system designed specifically for unfinished attic spaces. Avoid cutting boards in your attic by easily installing your Attic Dek in 15 minutes. Sturdy and durable, each Attic Dek tile can support up to 250 pounds. The lightweight construction of these flooring boards eliminates the risk of sagging joists and protects the integrity of your space. The prefabricated plastic panel squares fit either 16" or 24" on center joist systems. Simply secure them to your attic floor joists with the included screws. Just like that, you have additional flooring space for storage or a sturdy stepping stone pathway to get to hard-to-reach spaces. Each has five prefabricated holes for screws to be secured into the attic floor joists. Don’t worry about wires, pipes, and ductwork. With this easy installation flooring system, every nook of your space is accessible. The Attic Dek also includes two notches designed to hold wiring on each side of the panels. Available in 24" x 16" squares (pack of four) or 16" x 16" squares (pack of six). Screws included.
