Adjusting Ring
Adjusting Rings are sometimes called extension rings and they eliminate the necessity of raising or replacing existing manhole frames on resurfacing projects. The cover recess is the same depth and diameter as the existing manhole frame.

Flanges can be a plate or ring to form a rim at the end of a pipe when fastened to the pipe. Flanges are external or internal ridges or rims that attach to another object. The term “flange” is also used for a kind of tool used to form flanges.
