The Alera ALESW504818BL is a heavy-duty, NSF-certified industrial wire shelving kit designed for demanding storage environments. It features four wire shelves mounted on four posts with leveling glides, spanning 48 inches wide, 18 inches deep, and 72 inches tall. The unit is built from strong welded steel wire with a powder-coated epoxy finish in black.

The snap-together design requires no tools and assembles in minutes. Shelves adjust in 1-inch increments for flexible configuration, and the unit can be set up as a single four-tier rack or converted into two separate two-tier units at 36 inches high each using the included conversion kit. The open wire design promotes air circulation and reduces dust accumulation, making it suitable for both dry storage and heated environments.

Each shelf supports up to 1,250 lbs. of evenly distributed weight, with a total unit capacity of 5,000 lbs. The kit meets ANSI/BIFMA standards and carries NSF food equipment certification for dry and heated storage use. Made in China. Compatible with optional casters, shelf liners, S-hooks, and shelf tags (sold separately).
