Abstract: The sink drain assembly (3-5) comprises a downwardly extending drain sleeve (3) integrally formed on the sink (1); a resilient, generally cylindrical mounting member (5) formed with an upper annular section (7) adapted to releasably engage the drain sleeve (3) and with a lower annular section (13) adapted to releasably receive an upper portion (12) of a garbage disposer (8,9); a clamp (14) removably attachable to the mounting member (5) in overlying relation to the upper (7) and lower (13) annular sections, and a strainer (64) having a radially outwardly extending gasket (63) adapted to establish a generally water tight seal between the strainer (64) and a splashguard (66) mounted on the upper portion (12) of the garbage disposer (8,9).
