Rubbermaid Commercial Palletote® lid is designed for cost-effective storage and transport. Use this rectangular lid with Palletote storage boxes, Nos. 9PP41 and 8Y221, sold separately. HDPE (high-density polyethylene) is stronger than LDPE (low-density polyethylene) and resists moisture and certain chemicals. Rounded corners and smooth contours allow lid to be wiped clean.
