About the OmniShelf 2-in-1 Magnetic Utility Shelf Introducing the first-ever 2-in-1 portable workstation and briefcase. Our unique hands-free design attaches to any surface – from telephone poles and the side of HVAC units to truck doors and factory walls – using your choice of industrial strength suction cups and/or magnets. Plus, the gap between the back and the magnets/cups serves as a file folder for important paperwork and our oversized mousepad offers a smooth desktop area for taking notes or completing paperwork. With a 40 lb capacity, you can hold all your workstation needs and easily transport them from jobsite to jobsite. The OmniShelf is made from heavy duty plastic and steel cables. It’s virtually indestructible, improves efficiency for field workers and is the ideal solution for any worksite!
