Bsc Preferred LKVR18B 3.5 in Sink Drain Grid Strainer

Product Description

The BSC PREFERRED LKVR18B is a 3.5-inch sink drain assembly constructed from Type 304 stainless steel for long-term corrosion resistance in wet environments. It features a vandal-resistant grid strainer with a perforated 3-inch grid pattern that captures debris before it reaches the drain line, reducing service calls for clogs. The tailpiece measures 4 inches in length with a 1.5-inch outer diameter, allowing connection to standard drain plumbing beneath the sink. Licensed plumbers and trade professionals install this drain in commercial kitchens, bars, laundries, and residential sink applications where durability and low maintenance are priorities.

This drain is suited for both residential and commercial sink installations, including kitchen sinks, bar sinks, and laundry sinks. The vandal-resistant grid design is especially appropriate for high-traffic commercial environments where standard basket strainers are prone to removal or damage. The 3.5-inch drain opening dimension is standard across a wide range of drop-in and undermount sink configurations. The stainless steel finish integrates cleanly with stainless steel sink decks and surrounding hardware.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and clear the under-sink cabinet before beginning work. Plumber's putty or a silicone sealant is typically applied at the sink flange to ensure a watertight seal against the sink deck. Do not overtighten the locknut during installation, as excessive force can crack porcelain or deform thinner gauge sink material.
