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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid brass body construction for corrosion resistance and long service life\u003c\/li\u003e\n\u003cli\u003eFully rotating spout with 30-inch reach and 41.125-inch spout height\u003c\/li\u003e\n\u003cli\u003e44-inch flexible hose with pre-rinse spray head for extended coverage\u003c\/li\u003e\n\u003cli\u003e1.2 GPM low-flow spray head conserves water while maintaining rinse performance\u003c\/li\u003e\n\u003cli\u003eQuarter-turn ceramic disc valve for smooth, consistent operation\u003c\/li\u003e\n\u003cli\u003eCertified to NSF\/ANSI 61 and NSF\/ANSI 372 lead-free standards\u003c\/li\u003e\n\u003cli\u003eSingle-hole concealed deck mount for clean, minimal countertop penetration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for single-hole deck mount applications in commercial kitchens, institutional sinks, and compatible residential setups requiring a concealed deck mount faucet configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation 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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 1.2 gallons per minute\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpout Height\u003c\/strong\u003e: 41.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpout Reach\u003c\/strong\u003e: 30 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Length\u003c\/strong\u003e: 44 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Quarter-turn ceramic disc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: Double lever\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Single-hole concealed deck mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Solid brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: NSF\/ANSI 61, NSF\/ANSI 372 (lead-free)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 24 inches x 4 inches x 7 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ELKAY COMMERCIAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LK543LC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELKAY","offers":[{"title":"Default Title","offer_id":67911178879282,"sku":"LK543LC","price":830.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a7784570ac330c9480c539c3f4dd63d.jpg?v=1791205729","url":"https:\/\/voomisupply.com\/products\/elkay-commercial-lk543lc-concealed-deck-mount-faucet","provider":"Voomi Supply","version":"1.0","type":"link"}
