These marine white ice chests have UV inhibitors to withstand long periods of exposure to sun, sand, and surf. Its rugged, impact resistant body resists warping, fading, cracking, denting, peeling, chipping and just about anything else you can put it through. Refrigerator quality liner is stain- and odor-resistant and the Ultratherm polyurethane foam insulation in the body and lid provides maximum cold retention. The hinged, waffle lid is designed to support up to 300 pounds. Other features (except on the 25 quart), include a fish-keeper scale on lid and threaded drain plug for easy hose hook up. Also, coolers 54 quart and up feature child safety latches. The 128 quart has a divider/cutting board that stores in the lid and the 162 quart cooler has replacement skids to protect the cooler bottom. Both 128 and 162 quarts come equipped with nautical rope and wood handles.
