Six tiers per unit and two units in the box, each rack rated to 4800 lbs in total with every individual shelf carrying up to 800 lbs by itself. That per-shelf figure is the number that matters when the load is dense rather than bulky, and it comes from the deck profile: the wire is formed into a V-shaped section whose folded geometry distributes weight along the shelf instead of letting it concentrate at the center, which is where flat mesh starts to bow. Shelf positions adjust along the uprights, so the two racks can be configured identically for a symmetrical wall or set differently when one carries bulk cartons and the other holds six closely spaced levels of small stock. The design is meant to be reconfigured later rather than committed to once. Assembly is tool-free and uses fixing clips instead of nuts and bolts, so both units can be standing in a fraction of the time a bolted rack takes, and either one can be taken down and rebuilt elsewhere without hardware loss. Anti-tip kits secure the frames, an addition worth having on units that stand 78.5 inches tall, and adjustable foot pads level each rack on a floor that dips. Each unit spans 48 by 18 inches, and the pair weighs 65 lbs together on the scale. Suited to a garage, kitchen, basement, or laundry area where dense storage has to go vertical.
