Abstract: The safe storage and transportation of tanks containing compressed fluids is facilitated by a carrier which, in a preferred embodiment, can hold up to six such tanks in stable, fixed relation. Each tank is positioned in a compartment formed by front and rear members and a pair of sidewalls. The front member has a plurality of apertures for receiving the valve stems of the tanks. The rear member has a plurality of apertures for receiving the bottle ends of the tanks. Locking members can be adjusted to selectively lock the bottle ends at the rear member. A buffer region is preferably formed in front of the front member using a spaced front wall surface to prevent inadvertent contact with the valve stems. The sidewalls have handles to permit easy lifting and placement of the carrier.
