ABSTRACT:
A flange structure formed from a plurality of joined flange segments is provided. The joined flange segments form a generally circular opening for a conduit. The generally circular opening has a perimeter formed from a first surface segment having discrete teeth and extending in a direction generally perpendicular to the faces and a second surface segment tapered toward one of the faces. The flange structure can be connected to a substrate by fasteners extending through two oval shaped openings connecting the two forces. At least one shim is attached to the flange segments about the circular opening. The shim has an inner surface with essentially the same surface configuration as the generally circular opening of the flange segments.
