Bsc Preferred LK35 Drain Strainer Basket 3-1/2 Inch Ss

Product Description

The BSC PREFERRED LK35 is a 3-1/2 inch sink drain strainer basket and tailpiece assembly constructed from Type 304 stainless steel. It is designed for standard 3-1/2 inch drain openings and fits flush against a 4-1/2 inch overall flange. The conical strainer basket uses a metal stem and rubber seal to capture debris and prevent clogging. The included tailpiece measures 1-1/2 inches O.D. by 4 inches in length and is chrome-plated brass. Plumbers and general contractors install this fitting in residential and light commercial applications where a polished, corrosion-resistant drain assembly is required.

The LK35 is suited for kitchen sinks, bar sinks, and laundry sink installations that require a standard 3-1/2 inch drain opening. The polished stainless finish makes it appropriate for exposed sink applications where appearance matters alongside function. The assembly is sold as a single unit and is appropriate for new installations as well as direct replacement of worn or damaged drain strainer and tailpiece combinations. BSC PREFERRED notes compatibility with BSC PREFERRED sinks and accessories including custom-sized sink grids and wood cutting boards.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson. Shut off the water supply and clear the sink trap before beginning work. Plumber's putty or a silicone sealant is typically applied under the flange before seating; follow local IPC requirements for drain fitting sealing methods. Do not overtighten the locknut, as this can crack the sink basin or distort the rubber seal.
