Abstract: A cart for transporting pressurized cylinders includes an adjustable body supported above a ground surface by a pair of wheels, and a pair of cylinder retaining bands affixed to the body for holding a pressurized cylinder. The body is vertically oriented and includes a lower tube portion and an upper arm portion partially situated within and slidable with respect to the tube portion. This tube portion includes an open channel defined by two spaced-apart parallel edges extending substantially the length of the tube portion. A shaft is affixed to a lower end of the arm portion and extends perpendicular to the longitudinal axis of the body and outwardly through the channel. The shaft is exteriorly threaded, and engages a nut which can be rotated to frictionally bear upon the tube portion. This has the effect of holding the arm portion and the tube portion in a fixed spacial relationship.
