TOUGH MASTER TM-GMS8940 Garage Storage Shelves are a 5 Tier storage solution for all your needs. With a highly durable heavy duty steel and galvanised metal frame, plus sturdy CARB P2-compliant MDF boards – with each tier capable of bearing 175 kg / 386 lb (evenly distributed and on a level surface) – these shelves are built to last. The robust steel frame can firmly hold the MDF board, making the shelf extra stable and safe. Each shelf on the heavy duty galvanised shelving unit has been thoroughly tested and is very stable and safe to use, with cross braces under each shelf to provide additional stability. The shelf levels adjust every 3.5cm to accommodate items stored on the metal garage shelves of small or large size. The guard hole design allows assembly without bolts or nuts for easy installation. The only tool needed when installing the storage rack is a mallet. The boltless shelving unit can be a vertical rack or horizontal workbenches, and is great for a variety of uses, including in the garage, supermarket, workshop, warehouse, kitchen, bathroom, gym, basement, and more. Boltless steel shelving can be customised to fit any warehouse space.
