Astacking frameis described in CLT training under “Storage Equipment” as a modular, interlocking system designed to support and stabilize loads stacked vertically. It prevents crushing or deformation of goods by transferring weight through the frame rather than the product itself. Stacking frames are especially useful for irregularly shaped items or products that cannot safely bear additional weight. They also allow flexible layout adjustments because they can be easily disassembled or moved as inventory needs change. In contrast, pallet racks are fixed systems, and bins or standard racks do not inherently prevent compression damage. The CLT program highlights stacking frames as essential for space optimization and product protection, supporting safe vertical storage without permanent rack infrastructure.
