Versatile, on-the-go spill containment berm features patented Rigid-Lock wall supports to maximize usable space inside the berm. One-piece design sets up fast and easy - deploys quickly for emergency spill response. Sturdy walls with stainless steel braces lock at 90° offering strong structural integrity. Black support hub constructed from a high-strength engineered nylon accepts anchors to withstand wind loads of up to 40MPH for reliable containment under high wind conditions. Supports resist extreme temperatures (-50°F to 160°F). When in the down position, they can withstand vehicle weights in excess of 11,000 lbs. (5,000 kg.) at each tire. Unobstructed sump offers larger storage and working area for oddly shaped machinery, transformers, and other leaky containers. Tough EnGuard™ PVC coated fabric provides broad UV and chemical resistance. FOB Shipping Point.
