Bsc Preferred LKQD35PT Polymer Disposer Flange 3-1/2 in

Product Description

The BSC PREFERRED LKQD35PT is a polymer disposer flange designed for kitchen, prep, bar, and laundry sink installations requiring a 3-1/2 inch drain opening. The flange ships with a removable basket strainer and a rubber stopper, covering the two most common drain-use scenarios: free-flow drainage with debris capture and closed-basin fill for washing or soaking tasks. The polymer construction is color-infused through the material rather than surface-coated, which eliminates the risk of paint scratching or chipping and maintains a consistent finish over the service life of the fitting. Licensed plumbers and finish carpenters typically install this fitting during fixture trim-out.

This fitting is suited for residential and light-commercial sink installations including kitchen, utility, prep, bar, and laundry applications. According to the manufacturer, it is compatible with garbage disposals designed for 4-1/2 inch flanges and select InSinkErator systems. It is also specified to coordinate with BSC PREFERRED Quartz Classic and Quartz Luxe sink lines, providing a matched aesthetic when used with those product families.

Installation Notes

Installation is performed by a licensed plumber during sink trim-out or disposal retrofit. Shut off water supply and disconnect drain plumbing before removing an existing flange. Follow local plumbing code requirements, which typically reference IPC or equivalent standards for drain fitting installations. Clean the sink drain opening thoroughly before seating the new flange to ensure a proper seal.
