Double Taper Petroleum Trailer

The double taper petroleum trailer is a popular DOT-406 trailer style.  The Heil double taper design has a 6” pitch to the center from both ends.  This drop allows the trailer to drain completely and quickly in level environments.  Versatile enough to be used in hauling many fluids, the double taper design excels in the unloading of products with a high viscosity, such as lube oils.
