The QUANTUM STORAGE SYSTEMS QP212474V3S1 is a freestanding polymer shelving unit measuring 24 inches wide, 21 inches deep, and 74 inches tall. It ships as a complete system including three open grid shelves, one solid grid shelf, removable shelf mats for each level, and four vertical posts. The all-polymer construction is rust-proof and corrosion-resistant by design, not by coating, making it suitable for wet, humid, and chemically active environments. Rated for up to 2,000 pounds of load capacity across the unit, it carries NSF certification and is manufactured in the USA. No metal components means no rust risk and no painting or recoating over the life of the unit.
This shelving unit is designed for commercial and industrial applications where moisture, humidity, or chemical exposure would degrade standard steel shelving. Typical install environments include food service kitchens, walk-in coolers, healthcare storage rooms, supermarket back-of-house areas, and janitorial or chemical storage spaces. The open grid shelf design promotes airflow and drainage, which is a requirement in many food service and healthcare facility inspections. The solid grid shelf provides a stable surface for smaller items or bins. The gray finish is a neutral fit for most facility environments.
Designed as an OEM-style replacement or direct-fit addition within the Quantum Millenia polymer shelving system. Specific cross-compatibility with other Quantum shelving accessories or add-on components should be confirmed against the manufacturer's current product lineup.
Assembly requires no tools in most configurations - Quantum Millenia posts and shelves typically snap or clip together by hand. Installers should verify floor load ratings before positioning fully loaded units, particularly in walk-in cooler or elevated floor applications. In food service or healthcare environments, installation must comply with local health department requirements and any applicable NSF facility guidelines. Shelf mat placement and removal should follow the manufacturer's instructions to maintain proper drainage on open grid levels.
