Global Industrial 504456 Bulk Storage Rack Add-on 3 Level

Product Description

The GLOBAL INDUSTRIAL 504456 is a heavy-duty add-on bulk storage rack unit designed for hand-loaded industrial and warehouse storage applications. It adds three shelf levels to an existing rack bay using a single upright frame and five deck supports per level. The upright frame is constructed from 14-gauge steel at 1.75 inches by 1.75 inches, and the beams attach without tools, seating into position via 12-gauge beam connectors with three hooks at each end for a positive, secure connection. Beam height is adjustable on 2-inch centers, giving installers flexible configuration options across the full 120-inch height. No deck is included; wire, wood, or steel decking is sold separately.

This add-on unit is suited for commercial warehouses, distribution centers, light manufacturing facilities, and storage rooms requiring high-density shelving. The formed step beam frame design delivers nearly double the per-level capacity of standard bulk rack configurations, making it appropriate for bulky or heavy hand-loaded goods. As an add-on unit, it shares an upright frame with an adjacent starter bay, reducing the total number of uprights required across a row and lowering the overall system cost per bay.

Installation Notes

Installation is typically performed by warehouse or facility maintenance personnel. Ensure the starter bay upright is plumb and anchored to the floor per local building and racking codes before attaching the add-on frame. Beams attach without tools, but all connector hooks should be fully seated and audibly clicked into position before loading. Do not exceed the rated load capacity per level, and always load from the bottom shelf up to maintain rack stability.
