The yel-Low Safety Dolly is a truly innovative and "indestructible dolly" for the any industry. It can carry mattresses, large flat screen TVs, bulk items like kayaks or Ping Pong tables, headboards, desks, sofas, chairs and most items up to 1000 lbs. With a powder-coated uni-body steel box, the yel-Low dolly sits 1/4in. lower than a 3in. floor dolly and 1in. lower than a 4in. dolly. It's about the height of a pallet. The low loading height allows 1 person to tilt an object to load it instead of lifting an object onto the dolly. The tilt versus lifting allows 1 person to load and go instead of 2 people loading or 4 people carrying. What makes this a truly innovative moving device is the post system that allows the dolly to be reconfigured for any job at hand. This product ships in approximately 14 days
