Designed to perfectly fit any drain with a 3-1/2 in drain opening, the BLANCO 3-in-1 BASKET STRAINER catches debris unsuitable for your drain. It has a tight, protective seal when in use so nothing goes down the drain that you don't want to. The strainer can be popped out and lifted out of the sink to be easily emptied into the garbage instead. The strainer also includes a cover to hold water in your kitchen sink as needed. The strainer basket pops out for easy rinsing, making life easier for all. Blanco Basket Strainer, 3-in-1, Stainless Steel
