The Andersen Company No. 522 Hog Heaven Dry Anti-Fatigue Modular Tile III is a static-dissipative mat that has a top surface made from a solid 20% recycled nitrile rubber, which provides excellent chemical and oil resistance. This closed cell nitrile rubber surface is molded to the cushion backing and not glued, which means it will not delaminate over time and will provide long lasting comfort. This surface will also remain flexible over the life of this product and will not curl or crack. The Hog Heaven mat is certified slip-resistant by the National Floor Safety Institute and recommended for many different applications in distribution, manufacturing and retail environments because of its outstanding anti-fatigue qualities. This mat is also welding safe. Unlike the original Hog Heaven Mats this style is linkable to fit any work area. This piece is a corner piece with connections on two sides and a black and yellow striped border on the other two.
