• GRADE 1 CERTIFIED, FIRE-RATED STRENGTH: ANSI/BHMA A156.13 Grade 1 certified and UL listed for a 3-Hour fire rating (ANSI/UL 10C No. R40842). Engineered for offices, private suites, and heavy-traffic commercial interior doors.
• F04 ENTRY/OFFICE FUNCTION: Outside lever locks by switch toggle or cylinder; latch retracts by key outside or by the always-free inside lever. Auxiliary dead latch resists shimming. Ideal for private offices and staff-only entries.

• WIDELY COMPATIBLE, EASY RETROFIT: 3-5/8" cylinder-to-spindle spacing and 2-3/4" backset match most commercial mortise lock cases, dropping into existing door prep with minimal modification. Fits doors 1-3/4" up to 2-3/8" thick.
• BUILT TO LAST, BACKED BY OAKMOORE: Reinforced 2-piece spindles resist forced-handle damage; 6-pin Schlage C keyway cylinder included with 3 keys. Backed by Oakmoore's long-life warranty and dedicated US-based support.
