The uniquely designed 2-tier vertical dumbbell rack holds 6 pairs of hex dumbbells. Each level is offset, allowing unrestricted access to dumbbells. Place it against a wall or center it in a room. Heavy-gauge steel construction offers maximum durability and better performance in less space. Best used with hex dumbbells up to 35 lbs. only. If used with SDR rubber-coated hex dumbbells, they may sit at an angle due to the thick handles.
