Abstract
An assembly for adjusting the elevation of a structure such as a manhole or a catch basin to be surrounded by pavement. A one-piece is formed to be inserted between a base rim and a cover of the structure. A lower member of the adapter is received in the base rim to be supported on an internal shoulder. An upper member extends outwardly of the lower member to receive the cover and upwardly to engage the upper end of the base rim and form an upward extension of the rim. The elevation of the structure may be increased by inserting the adapter between the base rim shoulder and the cover and decreased by removing the adapter from between the base rim shoulder and the cover. Additional adapters of identical construction may be inserted to further increase the elevation of the structure, all the adapters being nestable within one another.
