The Norris 730 Super Tech Cart features a rear wheel assembly to allow hands-free stabilization of heavy loads. It also boasts an upper level tray with a 100lb capacity, providing a stable working platform or cargo divider. A simple lift of the rear wheels locks them and a toe-poke can drop them back down. Amazing 400lb capacity and generous loading tray allows you to move anything from presentation and display equipment to a washer/dryer. Easy single-motion squeeze handle telescopes the cart open and closed.
