Abstract

A plastic stackable riser for providing a grade level access for underground components such as septic tanks, distribution boxes, and drop boxes, including a cylindrical side wall having a top free edge and a bottom edge. The top free edge defines a first end opening and the second bottom edge is connected to a generally inverted U-shaped connecting member which defines a channel shaped to receive the first free edge portion of an adjacent stackable riser. In use, a plurality of stackable risers are interlocked together so that the side walls all extend along common vertical axes to the underground component and provide a gas-tight, liquid-tight column above the underground component.
