The new ORBIS 40 x 48 StakCap Top Cap allows double stacking of stackable and rackable pallet loads. It is designed to secure 40″ x 48″ pallet loads for easier and more efficient material handling while enhancing the safety and maneuverability of double-stacked pallets. Plastic reusable top caps secure container loads to maintain uniform weight distribution and stability when in storage or transit. When the new 40″ x 48″ StakCap is combined with the ORBIS 40″ x 48″ StackR or Heavy-Duty Structo-Cell (HDSC) Pallets, economic and efficient unit loads are created. With the StakCap, pallet loads can be securely double-stacked for greater cube utilization and increased floor space in plants and trailers. Its low-profile design allows for a high nesting ratio, creating more floor space on plant, storage, and trailer floors. The 40″ x 48″ StakCap is a single-sheet thermoformed (HMWPE) top cap. The geometry of the StakCap allows the top cap to be used with ORBIS 24″ x 20″ and 24″x 16″ totes. The StakCap can be fully recycled at the end of its service life.
