Elkay Commercial LK543LC Concealed Deck Mount Faucet

Product Description

The ELKAY COMMERCIAL LK543LC is a single-hole concealed deck mount faucet built for demanding commercial and institutional plumbing applications. Constructed from solid brass, this faucet delivers long-term durability under heavy daily use. A fully rotating spout reaches 30 inches with a spout height of 41.125 inches, allowing unrestricted coverage over large sinks and prep areas. The 44-inch flexible hose and pre-rinse spray head support deep cleaning and rinsing tasks. Flow is rated at 1.2 gallons per minute, meeting low-flow requirements without reducing functional performance. A quarter-turn ceramic disc valve provides smooth, reliable shutoff, and a spout swing restriction pin gives the installer easy directional control. Double lever handles round out the control layout.

This faucet is suited for commercial kitchens, school cafeteria prep areas, laboratory sinks, and institutional settings where a pre-rinse spray and high-arc spout are needed. The single-hole deck mount configuration integrates cleanly into countertops and sinks that are already drilled to one-hole spec, keeping the installation footprint minimal. It is also appropriate for residential kitchen islands or utility sinks where professional-grade hardware is preferred. The concealed deck mount design keeps supply connections out of sight for a cleaner installation profile.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code. Shut off the water supply at the isolation valves and relieve line pressure before beginning work. Verify the mounting surface is drilled to the correct single-hole specification before securing the faucet body. Do not overtighten the mounting hardware against the deck surface, as this can crack ceramic or composite sink materials.
