The B275 is the half-height companion to Ronco's small cube tanks: 15.62 x 15.12 x 7.75 inches, 7 gallons in a squat square-plan molding. Same tidy footprint as its taller siblings, half the headroom required - the tank for the locker with a shelf in it or the bay with ducting overhead.
Seven gallons fresh-fitted runs a marine sink or camp galley on potable water in food-grade polyethylene; waste-fitted, the same B-series dual-role blank is a low gray water catch. Fittings are never pre-installed - print the drawing below, mark your locations on the square top face, and use the on-page fitting planner to spec the spin-weld or threaded fittings Ronco installs to your marks.
Eleven pounds empty, about 58 lb full; bed it flat and strap it, the whole job is an afternoon. Molded in Tustin, California, as every Ronco tank has been since 1974. Taller and larger square tanks are in our boat tank category, with the maker's complete range on the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
