Three tiers on a bolted metal frame hold up to 176 lbs each, 529 lbs across the whole rack, which covers a full hex dumbbell set rather than a starter pair. Spacing between the bars adjusts to 3 positions, so short chrome dumbbells and longer rubber-coated ones both sit securely instead of rolling loose. The upright layout puts all of that on a 31.5 by 12 inch footprint and stands 31.5 inches tall, which matters in a garage or spare room where floor space runs out before storage does. A stable bottom structure and non-slip foot pads keep the rack from shifting when you pull a weight off the top tier. It weighs 12 lbs and assembly is required. Because the spacing resets with the same bolts, the rack adapts later if the dumbbell set grows.
