Bsc Preferred LK25RT Rotary Lever Drain Fitting

Product Description

The BSC PREFERRED LK25RT is a rotary lever drain fitting designed for kitchen and laundry sink installations. It features a 4.5-inch OD stainless steel flange, a brass body, and a chrome-plated brass tailpiece, delivering a combination of corrosion resistance and long-term durability. The fitting includes a basket strainer to catch food scraps and debris before they enter the drain line, reducing the likelihood of clogs and keeping the drain clear. Licensed plumbers and experienced installers typically handle this type of drain fitting as part of a sink rough-in or replacement project.

This drain fitting is suited for residential kitchen sinks and laundry basins where a 3.5-inch drain opening is standard. It ships with a 2-inch OD tailpiece and a 1.5-inch OD by 4-inch tailpiece, providing flexible connection options to match the downstream drain configuration. The stainless steel flange measures 4.5 inches in outer diameter, fitting flush over standard sink drain openings. The rotary lever mechanism allows straightforward basket removal for cleaning without tools.

Compatibility

Designed for use with BSC PREFERRED sinks featuring a standard 3.5-inch drain opening. Consult the sink manufacturer specifications to confirm tailpiece size and drain connection requirements before installation.

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 cabinet below the sink before beginning work. Plumber's putty or a silicone sealant is generally applied beneath the flange to create a watertight seal at the sink deck. Do not overtighten the locknut, as this can crack the sink material or distort the flange seating surface.
