Abstract
A frame for a cover for one of a catch basin and a manhole having an inlet, the frame comprising: a frame skeleton having a hollow body having a first end and a second end, the second end being adapted to be inserted into the inlet of the catch basin or manhole, the frame skeleton having at least one flange extending laterally outwardly from the first end of the hollow body and a concrete sleeve disposed around the hollow body on an external surface thereof, the concrete sleeve being adapted to be disposed between the inlet of the one of the catch basin and manhole and the at least one flange, the concrete sleeve having a top surface abutting the under surface of the at least one flange, the under surface of at least one flange covering the top surface of the concrete sleeve.

A frame for a cover for one of a catch basin and a manhole, the one of the catch basin and the manhole having an inlet, the frame comprising:
- a frame skeleton having a hollow body, the hollow body having a first end and a second end, the second end of the hollow body being adapted to be inserted into the inlet of the one of the catch basin and the manhole, the frame skeleton having at least one flange extending laterally outwardly from the first end of the hollow body, a surface of the at least one flange facing the second end being an under surface of the at least one flange;
- and
- a concrete sleeve disposed around the hollow body on an external surface thereof, the concrete sleeve being adapted to be disposed between the inlet of the one of the catch basin and manhole and the at least one flange, the concrete sleeve having a top surface abutting the under surface of the at least one flange, the under surface of at least one flange covering the top surface of the concrete sleeve.
A method for making a frame for an inlet of one of a catch basin and a manhole, the method comprising:
- providing a frame skeleton, the frame skeleton having a hollow body, the hollow body having a first end and a second end, the second end of the hollow body being adapted to be inserted into the inlet of the one of the catch basin and the manhole, the frame skeleton having at least one flange extending laterally outwardly from the first end of the hollow body, a surface of the at least one flange facing the second end being an under surface of the at least one flange;
- and
- assembling a concrete sleeve around the hollow body to form the frame before placing the frame into the inlet of the one of the catch basin and manhole, the concrete sleeve being adapted to be disposed between the inlet of one of the catch basin and manhole and the at least one flange, the concrete sleeve having a top surface abutting the under surface of the at least one flange, the under surface of at least one flange covering the top surface of the concrete sleeve.
