Abstract
A manhole cover support is shown. It is used for raising the grade of an existing manhole cover-receiving structure having an upwardly projecting keeper with a rim at its top. The cover support comprises: a peripheral flange that at least substantially completely covers said rim, the flange including a bottom, an inclined seat for a manhole cover, and a cover keeper that rises from the outer periphery of the seat and has an upper rim that is correspondingly inclined; and means for anchoring the flange to a fixed part of the existing manhole structure.
