Many spill pallets are quite tall, which is very helpful in reaching the necessary containment capacities to meet the EPA spill containment regulations. But not so helpful when youre trying to load a full drum onto it or pouring into a drum thats at a dangerous eye level. Thats PART of the plus in the spill pallet plus line. The lower profile (8 3/4 in for all pallets except for P1) makes handling and pouring much easier and safer. The other advantage is the weight capacity. The spill pallet plus line is capable of handling more weight than the other pallets in our lineup.
