Our larger 28″ x 48″ cart is a great fit for larger portable CMM arms, such as 6.5ft (2 meter), 8ft (2.5 meter), or 12ft (3.5 meter) arms. It is still narrow enough to fit through a standard size doorway, and it includes three 3-1/2″-8 mounting rings for flexibility in mounting the arm relative the part being measured. The cabinet has locking cabinet doors as well as handles on both ends to ensure the cart is easy to maneuver. The inside of the cabinet is open to accommodate any fixturing, power supplies, printers, or computers that you may want to store inside. Whether you are looking to make better use of the arm you already own or looking to add a new portable CMM to you facility, a heavy-duty rolling granite cart is great investment that will allow you to measure with confidence for a very long time.
