Bsc Preferred LK18B Sink Drain Strainer 3-1/2 in Ss

Product Description

The BSC PREFERRED LK18B is a 3-1/2 inch kitchen sink drain strainer and tailpiece assembly constructed from Type 304 stainless steel. It fits standard 3-1/2 inch sink drain openings and includes an extra-deep 3 inch removable basket that catches food scraps and debris before they enter the drain line. The 1-1/2 inch O.D. tailpiece measures 4 inches in length, connecting the strainer body to the P-trap or drain arm below. Plumbers and fixture installers working on residential or light commercial sinks will find this a direct-fit replacement or new-construction accessory for standard sink configurations.

The LK18B is suited for kitchen sinks, prep sinks, bar sinks, and laundry sinks where solid debris capture is needed. The extra-deep basket design reduces the frequency of cleaning intervals compared to shallow-basket strainers. The built-in basket handle allows removal without direct contact with accumulated debris, keeping service clean and quick. This strainer is a practical choice for remodel work, new sink installations, or replacement of a worn or corroded existing strainer body.

Installation Notes

Installation is performed by a licensed plumber or experienced tradesperson. Shut off the water supply and clear any standing water from the sink before beginning work. Follow local plumbing code requirements, including applicable IPC provisions for fixture drain connections. Do not overtighten the locknut against the sink basin, as this can crack the sink material or deform the strainer flange.
