An improved coupling assembly (10) mounted on a corrugated deck (30) and embedded in a concrete partition, such as floor (100), to provide an opening through the deck and the floor, is described. The coupling is comprised of an inner conduit (13) mounted inside of an outer sleeve (11). A flange portion (15) is provided at one end of the sleeve and includes openings (19) for fastening means, such as nails or screws (21) that serve to secure the coupling assembly in position on the deck. The conduit is mounted to the inside (11A) of the sleeve to position the opposed open ends (13B) and (13C) of the conduit extending beyond the sleeve means and through an opening (50) in the deck. The sleeve enables the contact point between the sleeve and the conduit to be adjusted along the length of the conduit. This is useful in those situations where the conduit has been mounted in an existing building construction or where the mounting position between the conduit and sleeve needs to be adjusted. The coupling is then embedded in the poured concrete floor and fluid carrying pipes can be connected to the opposed open ends of the conduit. The partition need not necessarily be a floor, but instead can comprise a wall. The floor can also be sloped and an upper end of the conduit can be provided with a drain conduit (61) for removing liquid from the top of the sloped floor.
