Bsc Preferred LK27 Lever Operated Drain Fitting 3.5 in

Product Description

The BSC PREFERRED LK27 is a lever-operated sink drain fitting designed for kitchen, prep area, bar, and laundry sink installations. The top flange is constructed from stainless steel and the body from brass, delivering corrosion resistance and long service life in high-use environments. The fitting includes a 1.5-inch O.D. by 4-inch chrome-plated brass tailpiece, a conical strainer basket with a flexible stem, and a rubber stopper for flow control. Licensed plumbers and experienced trades installers typically handle this fitting as part of a new sink rough-in or drain replacement. The 3.5-inch drain opening fits standard commercial and residential sink basins.

The LK27 is suited for both residential and light commercial plumbing applications where a lever-operated drain with integrated strainer function is required. Typical installations include kitchen sinks, prep sinks, bar sinks, and laundry basins. The lever operation allows the drain to be opened or closed without reaching into the basin. The stainless steel flange blends with stainless steel sink decks common in commercial prep environments. BSC PREFERRED offers matching components including sink grids and cutting boards that pair with this drain fitting for a coordinated installation.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and clear the drain line before beginning work. Plumber's putty or a gasket is typically applied under the flange during seat-down to ensure a watertight seal. Do not overtighten the locknut on the tailpiece, as this can crack the sink basin or distort the drain body.
