The kit includes both the stopper assembly and the waste plug, and the most compelling reason to buy is the clear compatibility details - stopper screw threads of 5\/16 in - 18 and a waste plug sized 1.5 in x 1 1\/2 NPSM - which make it easy to confirm fit before purchase. The part is a basic, durable option intended for repair rather than upgrade.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete replacement kit:\u003c\/strong\u003e Includes both the stopper assembly and the waste plug so the drain is ready to install without sourcing extra parts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClear thread sizing:\u003c\/strong\u003e Stopper screw threads are 5\/16 in - 18, which helps identify compatibility with existing hardware before attempting installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard waste plug:\u003c\/strong\u003e Waste plug is 1.5 in x 1 1\/2 NPSM, fitting common tub drain openings designed for NPSM threading.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStainless finish:\u003c\/strong\u003e The stainless construction resists everyday corrosion and keeps the visible parts looking consistent with stainless fixtures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer backing:\u003c\/strong\u003e Delta states faucets and parts are guaranteed for a lifetime, providing reassurance about availability and support when used as intended.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis drain is aimed at homeowners, handypersons and plumbers replacing a Delta-compatible tub drain or repairing a leaking or damaged stopper.
