At 5.75 inches, the B272 is one of the shallowest tanks Ronco molds - 7 gallons stretched across a 24.25 x 12.5 x 5.75 inch wafer that fits where even its low-profile siblings cannot. Under a false floor, inside a step box, across the top of a wheel-well arch: if the space is a slot rather than a box, this is the 7 gallon tank that uses it.
The B-series dual-role design gives the wafer both careers. Fresh-fitted, its food-grade polyethylene carries potable water; waste-fitted, it is a pan-thin gray water tank for a shower drain that has nowhere lower to go. It ships blank - print the drawing below, mark your fitting locations, and use the on-page fitting planner to spec the spin-weld or threaded fittings Ronco installs to your marks.
Twelve pounds empty, about 58 lb full, and like every long shallow molding it wants continuous support under the whole base so it cannot bow. Molded in Tustin, California since 1974. Deeper alternatives at the same capacity are in our boat tank category; browse the full line on the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
