We have some "Single D & E Cylinder Carts" made by Responsive Respiratory for $25 each. These carts can hold single D/E oxygen cylinders. These metal carts have adjustable handles so you roll these around for your height. It also has a handle near the oxygen holder. You can roll around your tank and then stand it up using the front feet. The carts are all in really good shape with very minor cosmetic wear. Recycled Furniture here in Irving is where you can see these and some other medical furniture. We have several other types of office and school furniture too. Feel free to contact us for more info.
