For easy refilling of our MINI tanks (20 oz. and 2.5lb.) you can transfill from a larger tank like a 10lb., 15lb., 20lb. or even a 35lb. In order to draw the dense "liquid" gas from the tank you need to flip the tank upside down with the valve at the bottom. This bracket will hold any of these size tanks in the inverted position. The nylon webbing and cradle at the top holds the tank from falling over. All steel construction. Powdercoat finish.
