Bsc Preferred LK2 Sink Drain 3.5 Inch Rubber Stopper

Product Description

The BSC PREFERRED LK2 is a 3.5-inch sink drain with rubber stopper, constructed from Type 304 stainless steel for corrosion and rust resistance in wet commercial and residential environments. The drain features a 1.5-inch O.D. outlet with a 4-inch tailpiece, providing a secure, leak-resistant connection to standard drain assemblies. It ships as a single unit and is installed by licensed plumbers or qualified trade professionals in kitchen, bar, and utility sink applications. The stainless steel construction is suited for high-use environments where durability and long service life are required.

This drain is designed for use in kitchen sinks, bar sinks, and laundry or utility sinks in both residential and light commercial settings. The 3.5-inch drain opening matches the standard sink cutout dimension common to most single and double-bowl stainless steel sinks. The included rubber stopper allows the basin to be filled and drained as needed, making it practical for prep sinks and utility basins. It is specifically noted as compatible with BSC PREFERRED sink accessories and coordinates with other BSC PREFERRED drain and grid products.

Installation Notes

Installation is typically performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and clear the drain line before beginning work. Plumber's putty or a silicone sealant is commonly used to seal the drain flange to the sink basin. Do not overtighten the drain locknut, as this can crack the sink basin or distort the drain body.
