The Two-Wheeled Panel Dolly-also called caddy, handler, mover-are designed to transport oversized or cumbersome flat objects (e.g., plywood/drywall/laminate sheets, doors, tables, partitions, windows, countertops, mattresses) within the workshop, home, and a variety of other environments. The dolly's basic components include a slotted steel frame with side plates (or clamping jaws) that ride on pneumatic tires. Frame length/width, side plate height, and tire diameter vary, depending on make/model. Carrying capacity is around 300 pounds. Some types have adjustable locking side plates, lifting handles, and/or removable uprights for added vertical bracing as standard features or available options.
