The Cambro CBA215472VS4580 Camshelving® Basics Plus 4-tier polymer shelf kit is designed for commercial kitchens and restaurants that demand durable, efficient storage solutions. This add-on shelving unit features three vented shelves that promote airflow while preventing dust buildup, making it perfect for storing bulk items like boxes, trays, or trays of food. The included solid shelf is ideal for small items that would fall through the vents, providing versatile organization in tight spaces. Its polypropylene construction is corrosion-resistant and dishwasher-safe, ensuring longevity even in demanding environments. The unit’s 1,800-lb capacity and temperature range of -36 to 190°F make it suitable for a wide range of applications, from storage rooms to prep areas. The pre-assembled post connectors and wedges simplify assembly, while leveling feet maintain stability on uneven surfaces—a critical feature for professional kitchens where floor irregularities are common. Whether you're expanding your existing shelving system or starting from scratch, the Cambro CBA215472VS4580 offers a reliable, space-saving solution that meets NSF and commercial kitchen standards. Its gray polymer finish blends seamlessly with modern kitchen aesthetics while delivering the performance commercial chefs and facility managers rely on.
