For decades Rubbermaid's Model 4520-88 heavy-duty Service Cart Plastic 2 Shelf KD 2436-2 (24x36) has been considered the most durable of any types available.

Being made of quality polymer plastic means it won't dent, chip or bend and it's light weight provides extra maneuverability and quiet operation.  Unit capacity is a formidable 500 lbs while each tray is sized at 24" x 36".  The molded handle assembly includes a convenient cup holder and storage slot for organization while the casters are non-marking on lino floor covered office areas.

It is many of these benefits that has prompted Blueprint Specialties to use these carts as their main material handler.
