Bsc Preferred LK99 Drain Strainer Basket 3.5 Inch Stainless

Product Description

The BSC PREFERRED LK99 is a replacement drain strainer basket designed for use in commercial and residential sink applications. Constructed from Type 304 stainless steel, this strainer basket provides corrosion resistance suitable for wet, high-use environments. It ships with an integrated rubber seal and a 4-inch stainless steel tailpiece, giving installers a complete assembly ready for drop-in service. The basket opening measures 3.5 inches in diameter and is engineered to seat securely in compatible sink drain openings. Plumbers and facility maintenance techs install this component when replacing worn or damaged strainer assemblies in kitchens, prep areas, bars, and laundry spaces.

This strainer basket is appropriate for both commercial foodservice prep sinks and residential kitchen sinks that accept a standard 3.5-inch drain opening. The included 1.5-inch O.D. tailpiece connects to standard drain rough-in plumbing and the rubber seal reduces the likelihood of leaks at the basket-to-sink interface. Typical installations include replacement service on stainless steel sinks in kitchens, wet bars, and laundry rooms where debris filtration at the drain is required to prevent downstream clogging.

Installation Notes

Installation is typically performed by a licensed plumber or qualified maintenance technician. Shut off water supply and clear standing water from the sink before beginning work. Hand-tighten the basket assembly and rubber seal against the sink bowl before securing the tailpiece connection to the drain rough-in; avoid over-torquing the basket flange to prevent cracking the sink bowl. Work should conform to applicable IPC and local plumbing code requirements for drain and waste connections.
