ABSTRACT:
A floor or roof drain fitting includes a flanged tubular member for positioning in an opening to form a drain structure. A sleeve is engaged about the tubular member such as by threaded engagement therewith with the upper portion of the sleeve being of considerably larger diameter and provided with a plurality of circumferentially spaced finger-like sections which are frangible. Tubular members may thus be clampingly secured in an opening in a floor or roof to form a water tight drain fitting.
