Industrial WorkSafe--always a fan favorite--has been improved and expanded to fit today's more demanding workplace. We've taken out some of the excess weight...because not everyone longs for heavy mats and high shipping costs! We've given a choice of rubber formulations to give you a broader choice of price points and performance levels. And we've added new SKUs, so you now have the option of orange, yellow, and black beveled borders. Industrial WorkSafe is about giving workers the right option in even the toughest and most demanding workplaces. Overall thickness 5/8" (16 mm).
