Abstract
A frame for a cover for an inlet of one of a catch basin and a manhole is provided. The inlet has an inlet passageway having a first cross-sectional shape having an axis of symmetry. A hollow body of the frame defines a frame passageway and has a second cross-sectional shape having first and second sides opposite to one another. When the frame is installed, the hollow body has a lower end extending partially within at least one of the inlet passageway and a head portion reducing a surface area of the inlet passageway. The second cross-sectional shape is inscribed within the first cross-sectional shape, and a distance of the first side of the second cross-sectional shape to the axis of symmetry of the first cross-sectional shape is different from distance of the second side of the second cross-sectional shape to the axis of symmetry of the first cross-sectional shape.
