Bsc Preferred ILR4322R4 Drop-in Sink with Drainboard

Product Description

The BSC PREFERRED ILR4322R4 is a single bowl drop-in kitchen sink with an integrated drainboard, constructed from 18-gauge Type 304 stainless steel. The sink measures 43 x 22 x 7.625 inches overall, with a 16 x 22 inch rectangular bowl that provides continuous workspace for washing, dish stacking, and meal prep. A central 3.5-inch drain opening accepts standard garbage disposals. Sound-deadening pads reduce operational noise, and the lustrous grain finish resists scratches and blends surface wear over time. Manufactured in the USA, the ILR4322R4 is a durable, full-size sink built to handle high daily use in residential and light commercial environments.

This sink is designed for drop-in installation in kitchens, bars, commercial prep areas, and laundry rooms. The built-in drainboard channels excess water directly back into the bowl, keeping the surrounding countertop dry and providing a stable surface for hot cookware or air-drying dishes. The U-channel mounting system positions clips inside the channel rail, simplifying installation by eliminating the need to reach underneath the deck for each clip. The sink is appropriate for both new construction and remodel applications where a standard drop-in cutout is used.

Compatibility

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson following applicable IPC plumbing code requirements. Shut off the water supply and disconnect existing drain and supply lines before removing or installing any sink. Apply a continuous bead of silicone sealant around the underside of the sink rim before dropping into the cutout, then secure mounting clips inside the U-channel rail. Do not overtighten mounting clips, as this can distort the sink rim or damage the countertop substrate.
