The BSC PREFERRED LKQS35MC is a polymer drain fitting designed for kitchen and laundry sinks requiring a 3-1/2 inch drain opening. Constructed from color-infused polymer, it resists chipping, scratching, corrosion, and staining under everyday service conditions. The fitting ships in a Mocha finish and includes two functional components: a removable basket strainer that captures food debris to help prevent drain clogs, and a rubber stopper that allows the basin to be filled for soaking. Licensed plumbers and experienced DIYers install this fitting as a matched-finish accessory for compatible quartz sinks.
This drain fitting is intended for residential kitchen sinks and laundry prep sinks where a coordinated drain accessory is required. It is sized for the standard 3-1/2 inch drain opening found in most kitchen sink basins. The Mocha finish is engineered to visually coordinate with BSC PREFERRED Quartz Classic and Quartz Luxe sink models. No additional cutting or modification of the drain opening is required for a properly sized installation.
Designed for use with BSC PREFERRED Quartz Classic and Quartz Luxe sinks in the Mocha finish. Fits sink drain openings measuring 3-1/2 inches.
Installation is performed by a licensed plumber or qualified DIYer familiar with sink drain assemblies. Shut off water supply and ensure the sink basin is dry before installing or removing the drain fitting. Follow all applicable local plumbing codes, including IPC requirements for drain fittings. Do not use abrasive tools or harsh chemical cleaners on the polymer body, as these may damage the finish.
