ABSTRACT:
A conduit end cap structure (e.g., a floor drain assembly) that is securely attached to the conduit and aesthetically pleasing. The end cap of the conduit comprises a perforated plate. Anchor supports extend from the substantially concealed underside of the plate, each providing support for an anchor that is received by an anchor receiving structure on the conduit to securely attach the plate to the conduit near its opening. The anchor may be in the form of a fastener (e.g., a set screw), and the anchor receiving structure is in the form of a channel provided on the inside wall of the conduit opening. The fastener extends into the channel, thereby securely retaining the plate to prevent it from dislodging from the conduit end.
