The uniquely designed 2-tier vertical dumbbell rack holds 6 pairs of hex dumbbells. Each level is off-set, 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 35lbs. only. If used with SDR rubber coated hex dumbbells, they may sit at an angle due to the thick handles.
