Abstract: A scuba rack for holding four scuba tanks with back packs and regulators attached securely in place. The scuba rack is especially suitable for securing scuba or diving tanks, with accessories attached, in an automobile, on the deck of a boat, raft or the like. A flat bottom support has four shallow cylindrical recesses in its upper surface for accommodating the bottoms of four scuba or diving tanks. The cylindrical recesses are symmetrically arranged about a rigid vertical upright post extending centrally from the bottom support. Four flexible straps are attached to the upper portion of the vertical upright and can be stretched to loop over the valve units of the respective diving tanks to force them inwardly against the vertical upright and downward securely against the bottoms of the cylindrical recesses.
