A simple lift of the rear wheels locks them upright when not in use 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. Sleek design and limited lifetime warranty.
