ErgoDeck WHITE floor tiles are Silicone free and designed for "body in white" applications, where metal forms are painted and inspected. The extremely light color of ErgoDeck WHITE reflects the light rather than absorbing it. As the light bounces off the tiles, it highlights blemishes in the paint. ErgoDeck WHITE is a SOFT, 68 durometer compound for increased worker comfort and productivity. Ideal for large and custom-sized areas, the super-sized, 18" x 18" tiles quickly assemble and securely connect to create "a floor above a floor". To complete this heavy-use ergonomic floor, the optional 6" wide safety ramps and corners have countersunk holes so your overall configuration can be attached to the floor as a more permanent installation. 7/8" overall thickness.Available in two designs:No. 564 – for areas with vertical airflowNo. 566 – where airflow is not a consideration
