Our two stack racks designed specifically for door and window storage may also be converted into a picking cart by using the “Stack Dolly”. Choose between either three sided stack rack (our most popular unit 46”d x 92” overall or the slightly larger 48”d x 98”w unit) for the best means of storing or staging your millwork. Both units have channel mounting brackets for positive-foundation stacking – allowing for the stack of three-units high fully loaded. The ends and back bars may be removed for easy storage when not in use. Dividers may be used (sold separately) to separate/protect the material on the rack. (Material weight bearing capacity of 2000 pounds per rack.) Both units come with ‘fork-stirrups’ throughout to allow for secure movement of the rack by a forklift, even when the rack is unbalanced.
