Constructed from steel and finished in Satin Chrome (US26D), this Grade 1 lockset is engineered to withstand the mechanical demands of high-traffic entryways. The 3.5-inch rose plate provides a clean, professional appearance against the door face. Grade 1 rating indicates the highest ANSI\/BHMA performance classification for cycle endurance, security, and force resistance, making it appropriate for commercial installations where durability and code compliance are non-negotiable.\u003c\/p\u003e\n\u003cp\u003eThis lockset is suited for commercial and institutional entry doors that require a fire rated hardware assembly. Typical applications include office buildings, schools, healthcare facilities, and other occupancies where fire-rated door assemblies are mandated by local building codes. The keyed entry function restricts outside access while allowing free egress from the interior, which aligns with IBC and NFPA 80 requirements for fire door hardware. A licensed locksmith or commercial door hardware technician typically handles installation in these environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFire rated construction for use on listed fire door assemblies per applicable code requirements\u003c\/li\u003e\n  \u003cli\u003eGrade 1 ANSI\/BHMA classification for maximum cycle endurance and security in commercial applications\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides structural integrity under forced-entry and high-traffic conditions\u003c\/li\u003e\n  \u003cli\u003eSatin Chrome (US26D) finish offers a professional, low-glare appearance with corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e3.5-inch rose plate suits standard commercial door preparations\u003c\/li\u003e\n  \u003cli\u003eKeyed entry function controls outside access while maintaining free egress from the interior\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation lever lockset for commercial fire-rated door assemblies requiring a Grade 1 keyed entry function.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed locksmith or qualified commercial door hardware technician. Before installation, verify the door and frame assembly carry the appropriate fire rating label and that hardware is listed for use on that assembly per NFPA 80. Confirm the door preparation matches the lockset rose and latch dimensions before mounting. Do not install on doors where the existing fire label would be voided by field modifications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLockset Type\u003c\/strong\u003e: Entry Lever\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFire Rating\u003c\/strong\u003e: Fire Rated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLockset Grade\u003c\/strong\u003e: Grade 1 (ANSI\/BHMA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome (US26D)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRose Diameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: YALE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: AU546F-US26D-KD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YALE","offers":[{"title":"Default Title","offer_id":51712577896754,"sku":"AU546F-US26D-KD","price":670.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be0e557ce8559c89840d11b2b8cfcc77.jpg?v=1788486790","url":"https:\/\/voomisupply.com\/products\/yale-au546f-us26d-kd-fire-rated-entry-lever-lock","provider":"Voomi Supply","version":"1.0","type":"link"}
