  • Patent number: 4306738
    Abstract: A flanged fitting comprises a flanged tubular member for positioning in an opening in a floor or roof to form a tubular conduit therethrough. The flange on the fitting may comprise a closet flange, a floor drain flange, or a flat roof flange. Additionally, the flange may be provided with an upstanding tubular member to which a secondary tubular conductor may be attached in the nature of a vent. A sleeve is engaged about the tubular member such as by a clamping member thereon with the upper portion of the sleeve being of a considerably larger diameter and provided with a plurality of circumferentially spaced finger-like sections which are frangible. The flanged fitting may thus be clampingly secured in an opening in a floor or a roof in a desirable location in an opening therein to serve an intended purpose.
