Wearwell 24/Seven Solid NBR is a high performance, 3"x3" (91 x 91 cm), interconnecting rubber anti-fatigue mat. Suitable for wet, dry and oily conditions. These resilient modular mats are 5/8” (16mm) thick and tough enough to handle 24/7 shift operations, but supple enough to provide cushioned support where it’s needed. Because of its modularity, 24/Seven can be positioned to cover large flooring areas, single workstations and assembly lines. For extra safety attach optional 3 x 39 in. (8 x 99 cm) beveled yellow safety edges.
