Two 81-quart carriers stack into one column here, and each keeps food hot or cold for 4 to 6 hours thanks to a seamless double-wall LLDPE shell filled with polyurethane foam and sealed by an inlaid gasket ring. The door swings 270 degrees so loading and unloading full-size pans (not included) is unobstructed; 8 shelf dividers hold up to 5 full-size pans or a mix of shallower ones. Each unit measures 24.5" x 16.5" x 29" outside and 21" x 14" x 17" inside, with stainless steel hardware and nylon fittings. The pair weighs 66 lbs and ships in two boxes. Food-grade LLDPE resists cracking and impact on delivery routes, and the non-electric design works in canteens, restaurants, hotels and off-site catering where an outlet is not available.
