Built for demanding industrial environments, these add-on units provide the strength and flexibility required to store tools, supplies, equipment, boxes, bins, and inventory.

Engineered as part of Hallowell’s Hi-Tech Steel Shelving system, these units deliver dependable performance in warehouses, manufacturing facilities, stockrooms, maintenance areas, and commercial storage spaces. Each shelf is constructed with a tubular welded box beam on both the front and rear, providing exceptional structural strength and long-term durability. Exclusive triple-bend side flanges further reinforce the shelves, while lapped and welded corners ensure reliable support for everyday industrial use.

Shelves are punched to accept dividers and install easily using only four shelf clips, allowing for quick adjustments and flexible configuration. The shelving system is designed to work with beaded front posts, angle back posts, T-posts, and H-posts, providing adaptability for a wide range of facility layouts.

Hallowell’s medium duty shelving line offers the strength needed for most industrial applications while maintaining the versatility required by modern storage environments. A full range of accessories—including full and partial dividers, label holders, swinging doors, post splices for multi-level systems, and foot plates—is available to further customize your storage system.

Manufactured with durability and precision, these shelving systems are Made in America and designed to withstand years of daily use without compromising structural integrity.

An Add-On Unit is designed to connect directly to an existing starter unit, allowing you to extend shelving rows while using fewer posts and reducing overall system cost.

Add-on units share one set of posts with the starter unit, making them ideal for expanding storage capacity without taking up additional floor space.
