Larsen Supply 03-1151 Deep Mount Sink Strainer 3.5in Ss

Product Description

The LARSEN SUPPLY CO., INC. 03-1151 is a stainless steel kitchen basket sink strainer designed for deep-mount installations where a standard short-shank strainer will not reach. The long shank construction accommodates thicker sink decks and deep-mount basin configurations commonly found in commercial prep sinks and heavy-duty residential kitchens. The strainer body measures 3.5 inches in outer diameter and ships with a locknut and washers included, giving the installer a complete assembly ready for drop-in service. This is a straightforward OEM-style replacement or new-install component suited for licensed plumbers and experienced trade professionals handling sink rough-in or fixture replacement work.

This strainer is intended for kitchen sink applications requiring a deep-mount fit. The long shank design addresses installations where sink material thickness or basin depth would cause a standard strainer to seat improperly or fail to engage the locknut with adequate thread engagement. It is packaged individually and sold in a unit of measure of each, with a package quantity of four units per case. Typical installations include residential kitchen sinks with thicker stone or solid-surface decks, as well as light commercial basin applications.

Installation Notes

Installation is typically performed by a licensed plumber during sink rough-in, fixture replacement, or drain service. Shut off the water supply and drain the p-trap before removing the existing strainer. Apply plumber's putty or a compatible sealant around the strainer flange before seating it in the drain opening, then secure the locknut from below to the manufacturer's recommended hand-tight-plus specification. Follow all applicable IPC and local plumbing code requirements for drain fitting installations.
