The B453 is a 41 gallon shell shipping at 51 lb - middle of the road on wall, generous on capacity, the tank you spec when the installation is ordinary and the budget of weight and space is tight but not desperate. Not every bay needs the armored molding; most need exactly this.
Being a B-series molding, it is dual-role by design. The same shell becomes a fresh water tank or a gray/black waste holding tank depending on the fittings, and Ronco installs those per order - spin-welded or thread-mounted at whatever positions you mark. Print the drawing below, mark inlet, outlet, and vent from your plumbing plan, and run the picks through the on-page fitting planner before ordering.
Full, the 41 gallons weighs about 342 lb, which is the number your shelf, straps, and chocks should be designed around. Molded in Tustin, California by Ronco, rotomolding tanks since 1974. The neighboring capacities up and down from here are in the boat tank category; every Ronco shape we carry is on the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
