Our Variable Height Universals live up to their name as they can be used for many different things including collapsible medical carts. You can change the height with the equipment still loaded on the platform. The model 290 is our biggest workhorse and they too can be used as collapsible medical carts. With the 65” long platforms, there is storage space for several pieces of equipment. The Salesmaker model 289 works the same way as the Heavy Duty folding hand trucks, model 290. A 50” long platform makes it more compact. These collapsible products have a 20 year history of reliability and can also be used as collapsible medical carts.
