The Oatey 621APVC Bath Waste and Overflow Trim Kit provides the essential components for connecting a bathtub to a plumbing drainage system. This kit includes a lift-and-turn drain stopper and an overflow plate, both featuring a chrome finish for exposed parts. It also contains the necessary PVC drain shoe and overflow elbow components, which are designed for solvent welding to 1-1/2 inch nominal pipe size (NPS) Schedule 40 PVC drain, waste, and vent (DWV) piping. Classified as a "half kit," this product does not include the connecting overflow pipe or the tee fitting; these items must be supplied separately by the installer to complete the waste and overflow assembly. The lift-and-turn mechanism allows for simple control of the bathtub drain, preventing overfilling and facilitating water removal.
