Underneath the sink, a rubber gasket, metal washer, and large locknut or retainer tightens the body to the sink. A straight tailpiece mounts to the strainer body with a threaded coupling. Slip-joint couplings connect the tailpiece, the main parts of a drain trap, and a short threaded nipple at a tee in the drainpipe.
