Featuring a positive locking system, this 3' x 3' mat not only fights fatigue, it also connects firmly with other components, allowing you to move an entire row of flooring without reconfiguring. This makes maintenance quicker and less labor-intensive. Choose additional panels, male and female ramp edges and corners to suit your space without cutting components to fit. The open-grid design allows for drainage, and the nitrile rubber compound resists petroleum-based product.
