Made of recycled polyethylene, these pallets resist chemical attack from hazardous acids, caustics and solvents. The oversized sump holds the contents of a 55-gallon (200-L) drum in the event of leak or rupture—meeting or exceeding the most stringent spill containment regulations. Seamless construction eliminates leaks. Self-locating grates lift off for quick clean up. Black pallets contain 100% recycled content—their dark color hides grime and dirt to keep your workplace looking clean. High visibility yellow pallets contain 35% recycled polyethylene.
