Our functional folding mechanic mat is the ideal solution for working on hard or irregular surfaces. Whether in the shop, home or on-the-go the mat is made of molded plastic with a foam filled padding on each panel for support and the carbon fiber texture applied resists slipping. Each of the four panels are connected by six steel poles and steel hinges making folding and unfolding easy. Since the panels are foldable you can double-up the panels when in a smaller space as well as adding extra padding on the knees. Dimensions are 19” W x 10-½” L when folded, and 19” W x 42” L when open completely.
