The B449 threads 32 gallons through a 44.5 x 15.5 x 12.5 inch envelope - long, narrow, and barely a foot tall, the shape that follows a hull side, runs outboard of an engine, or slides down the utility chase of a trailer. Tanks like this recover space that square moldings write off.
It is a dual-role B-series shell: order it with potable fittings for fresh water service or sanitation fittings for gray/black holding. The 44.5 inch run gives you real latitude on placement, so print the drawing below, mark where along the length each fitting should sit to meet your plumbing, and Ronco spin-welds or thread-installs to those marks. The on-page fitting planner covers sizes and styles.
The blank ships at 85 lb and holds about 267 lb of water at full, distributed along its length - support it continuously rather than at the ends. Rotomolded in Tustin, California, where Ronco has molded tanks since 1974. The slimmer and shorter variations on this format are in the boat tank lineup and the RV water tank lineup. OneSource Plastics is an authorized Ronco Plastics dealer.
