The unique design and craftsmanship make this mat easy to handle and install. The Skymaster™HD is made from heavy duty rubber compound for industrial strength. 3' x 3' snap together tiles can be easily assembled for coverage of large areas or individual work stations. A 5/8" thick worker platform with an ergonomic bubble pattern provides maximum anti-fatigue comfort in dry industrial environments. A tooled grid of 12" x 12" sections on the underside of the mat makes further customization quick and easy.
