Hooks rather than fixed shelves hold the five planter boxes on this frame, so any box can be lifted off for repotting and hung back without tools. The boxes stagger across 3 tiers to keep sunlight reaching the lower rows, and each measures 23.5 by 8.5 by 3.5 inches with a 55-pound rating. A rustproof painted metal frame carries the load, tied together by multiple screws and 2 crossbars that lower the center of gravity and steady the unit on a deck. Polyethylene boxes are lightweight, shatter resistant, and hold up to weather. The whole planter measures 25.5 by 36 inches on the ground and stands 31 inches tall at 15.5 pounds, a working height that avoids constant bending.
