A molded plastic extension member for use in increasing the height of manholes, or catch basins when surfacing or resurfacing a roadway. The extension member may be formed having a sloping upper planar support surface to thereby adjust the angle of the catch basin support frame or the manhole cover support frame. An outer surface of the extension member includes indicia that allows the user to align the slope of the upper planar support surface parallel with the roadway surface. When several sloped extension members are stacked, the indicia may be used t...


[ What is claimed is:] [1.] An extension adapted to be disposed between an open top surface of a base of a manhole or catch basin and a bottom surface of a support frame, said extension comprising:a molded plastic member having a central opening for access therethrough and a shape conforming to an open top surface of a base, and further having outer, central, and inner concentric, spaced-apart walls, each wall having inner and outer surfaces, wherein a first planar support surface extends perpendicularly from at least one of a lower and upper edge of sai...
