Bsc Preferred LK87RT Rotary Lever Drain Fitting 3-1/2 in

Product Description

The BSC PREFERRED LK87RT is a rotary lever-operated drain fitting designed for kitchen, bar, and laundry sink installations. Built from chrome-plated brass, it features a 1-1/4 inches O.D. overflow connection and a 4 inches tailpiece. The stainless steel top flange measures 4-1/2 inches O.D. and provides a durable, corrosion-resistant seating surface. A basket strainer captures food particles and debris before they enter the drain line, reducing the risk of clogs. This fitting is sized at 3-1/2 inches and is intended for professional plumbing installation in residential and light commercial sink applications.

The LK87RT suits 3-1/2 inch sink drain openings found in kitchen sinks, bar sinks, and laundry tubs. The rotary lever mechanism allows users to open and close the drain without a separate stopper, streamlining the drain assembly. The chrome finish coordinates with standard chrome faucet and accessory trim in residential and commercial kitchens. The included basket strainer functions as both a waste filter and a drain closure device, making it suitable for utility and food-prep sink environments where solid waste management matters.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and ensure the sink area is clear before beginning work. Plumber's putty or a supplied gasket should be used to seal the flange to the sink deck per the manufacturer instruction. Verify all slip-joint connections are hand-tightened and then snugged with channel-lock pliers before testing for leaks.
