Tackle big storage jobs with this 5-tier garage shelving unit rated for a total 3000 lb, with 600 lb of capacity per shelf. SPCC carbon steel and a powder-coated finish resist rust, oxidation, and scratches across the 18 x 48 x 78 inch frame. A quick-adjust mechanism with locking clips lets you set shelf spacing in 38 mm increments, and the rack splits into two units for low-clearance spaces like basements or stairwells. Press-fit assembly requires no screws, and a rubber hammer and gloves are included for an easy build.
