The 42H is a wall of a tank: 91.5 inches long, 16 inches tall, and only 7 inches thick. Fifteen gallons of holding capacity stood on edge like a panel. Builders spec this shape to run vertically along a frame rail, behind a basement wall, or flat against the inside of a skirted chassis where the only free dimension is length and height, not depth.
A molding this extreme demands material, and it gets it: 36 lb of polyethylene, the heaviest blank in Ronco's 15-gallon class, keeping those long thin panels from bowing when about 125 lb of waste water pushes on them. Mount it with support along the full run - a tank nearly eight feet long should never hang from its ends alone.
Two other long-format holding tanks trade height for width: the 44H lies flat with 12 gallons at 80.75 x 14 x 6.75 inches, and the 43H carries 20 gallons at 81 x 11 x 7.75 inches.
