A universal lid for industrial or commercial large size solid waste containers, has a ribbed single layer central portion and a peripheral edge having a hollow double wall boxed configuration. The boxed perimeter may have a predetermined height such as approximately one inch, and the lid is provided with hinge lugs having a vertical extent substantially more but not more than twice than said predetermined height. In addition, the lids have substantial symmetry so that the lids may be stacked and nested with alternate lids oriented in opposite front-to-back directions. With this type of lid, the advantages of both single layer and double layer lid constructions may be realized.
