ABSTRACT:
A drain tube assembly for use with a lavatory or other plumbing fixture is disclosed. The lavatory has a basin, a lower drain outlet having an internal threaded bore, and a one-piece drain structure having a drain tube adjacent one axial end, an attachment sleeve adjacent an opposed axial end which is radially outwardly threaded, and a radially extending flange there between. When attached, the drain structure has an axial path extending through the attachment sleeve, flange, and drain tube to carry liquid from the lavatory out the drain tube. In a first position the flange can form a clamp member if the assembly is to be mounted through a counter top. Alternatively the flange can in a second position form a base for the lavatory when the lavatory is suspended. Movement between the positions is created by varied degrees of threading the sleeve into the lower drain.
