Mobile Roll Files are very popular for office settings. They are made of sheet metal which gives them a good amount of strength while maintaining a lightweight product that is very mobile. All drawings, blueprints, sketches, x-rays, maps and posters are rolled and stored in the Upright Roll File in a vertical fashion. This allows for minimal office floor space to be utilized while still providing ample space for a large amount of drawings to be stored neatly. What makes this product so popular among offices is the mobility factor. Wire Upright Roll Files come with casters that make your organized documents moveable around the office and conference rooms. The sheet metal structure provides great support and organization while adding a modern and professional look to your office. We recommend purchasing multiples for larger businesses who need to keep multiple large projects separate and organized.
