Elkhart Plastic tanks are manufactured to meet quality and health safety standards. With fewer impurities, these tanks are strong enough to take the bumps and bangs without compromising the security of your waste-water holding system. Elkhart Plastics uses a process called roto-molding in which high-density plastic is rotated and molded into shape. This process creates a seamless tank in which the walls are of equal thickness, with no weak spots to cause trouble later. It is this process that has earned Elkhart Plastics the reputation for quality tanks.

Dimensioned Print and Gallery Views

The retained print shows an84 x23-inch overall footprint,11 9/16-inch maximum depth and7 1/2-inch shallow-end depth. The upper band is3 inches deep; the body below it is20 inches wide. The sloped underside and inset outlet end are important clearance details. Earlier12-inch display depth has been corrected to the print dimension.

Compare the entire drawing with your existing tank, mounting supports and plumbing. The print shows an outlet at the deep end but does not dimension its bore diameter, projection or every molded transition. It does not locate top openings; no top fittings were added to the visualization.

The four views and rotatable model are reconstructed from the print, not measured manufacturing CAD. Undimensioned outlet details, end setback, cross-slope and edge blending are illustrative. The original dimensioned blueprint remains the fitment reference.
