3.5-inch Kitchen Sink Drain: Fits 3.5-inch sink drains with a 4-inch integrated flange, compatible with any standard residential/commercial kitchen and bar sink. 304 Stainless Steel: The drain cup, lid, and strainer basket are made of 304 stainless steel and polypropylene (PP), which are waterproof, rustproof, high-temperature resistant, and corrosion resistant. The featured ball-lock basket ensures a perfect seal; lift the strainer basket to drain and press it down to retain water. Integrated Sink Drain Kit: The simple sink drain kit fits kitchen sink drains and bathroom sink drains with an overflow connector for connecting to an overflow pipe drain or dishwasher drain. Quick-clean, odor-proof sink drain trap: The P-type drain trap features a water-sealed, odor-proof cup design, providing double odor protection and sealing against smells.

Easy and quick installation: This drain is easy to install. The drain bolt screws in from the top, eliminating the need to struggle to remove nuts from under the sink. It features a high-quality rubber seal that conforms to the contours of your sink, ensuring it won't leak when filled with water.
