A hollow bushing extension extends downwardly from the center opening and terminates in an open lower portion with external threads. A hollow attachment bushing having a center opening is threadably secured around the lower portion of the bushing extension and extends downwardly therefrom. The attachment bushing has a lower open end with at least one crossbar extending thereacross. A bearing hub is formed in the center of the crossbar on the center axis of the aforesaid center openings. A vertically disposed threaded aperture is located in the hub and is adapted to threadably receive a connecting stud from a drain strainer or closure valve.
