The CX Black & Yellow 4-Tier shelving unit is a modular storage solution manufactured from High-Density Polypropylene. This material choice is specifically beneficial for damp basements or outdoor areas, as the plastic frame is naturally resistant to oxidation and rust. The unit features a ventilated shelf design which promotes airflow around stored items, helping to prevent the buildup of moisture or mold in humid conditions.
Design specifications highlight a 20-inch depth, which provides a more stable center of gravity compared to shallower residential racks. This added depth helps prevent the unit from tilting forward when loaded with heavy bins. While the shelves are built to handle daily household use, it is a practical reality that long-term exposure to very high heat in a garage—combined with heavy, concentrated loads—may lead to slight bowing of the plastic over several years.
Assembly and Practical Use
The assembly relies on a friction-fit post system. To ensure the unit reaches its full stability potential, it is helpful to use a rubber mallet to seat the posts completely into the shelf sockets. This prevents the "leaning" that can occur if the joints are only partially connected. Because it is modular, the feet and top caps can be interchanged, allowing multiple units to be linked together if you need to create a longer wall of storage.
If you require a storage solution that can be easily moved around the room as you work, the PrimeZone 5-Tier rolling rack includes wheels for better mobility on flat surfaces.
