The BSC PREFERRED LKPDQD1MC is a 3.5-inch polymer disposer flange finished in Mocha, designed for use in kitchen sink drain applications. The flange serves as the mounting interface between a garbage disposal unit and the sink drain opening. Constructed from high-quality polymer with fully infused color technology, it resists chipping, scratching, corrosion, rust, and stains without requiring surface coatings that can wear away over time. Plumbers and kitchen installers specify this type of fitting when coordinating drain hardware to match a specific sink finish. The Mocha color is formulated to coordinate with BSC PREFERRED Quartz Classic and Quartz Luxe sink lines, delivering a consistent aesthetic across the sink installation.
This disposer flange is suited for residential kitchen installations where the drain hardware must match a quartz composite sink finish. It accommodates garbage disposals that use a 4.5-inch flange opening, including select InSinkErator models. It is also applicable in kitchen prep areas or laundry spaces where a finished polymer drain fitting is specified. The part ships as a single unit and is intended for direct replacement or new installation alongside BSC PREFERRED sink products, including compatible stainless steel grids and cutting boards sold separately.
Designed to coordinate with BSC PREFERRED Quartz Classic and Quartz Luxe sinks in Mocha finish. Accepts garbage disposals that fit a 4.5-inch flange opening, including select InSinkErator models.
Installation of a disposer flange is typically performed by a licensed plumber or qualified installer. Shut off the water supply and disconnect any existing disposal unit before beginning removal or installation of the drain flange. Standard plumber's putty or the manufacturer-supplied gasket is typically used to seal the flange to the sink basin. Follow local plumbing code requirements, including applicable IPC provisions, for drain fitting installation.
