Yale AU546F-US26D-KD Fire Rated Entry Lever Lock

Product Description

The YALE AU546F-US26D-KD is a fire rated entry lever lockset built for commercial and institutional door openings that require both access control and code-compliant fire protection. 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.

This 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.

Installation Notes

Installation 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.
