📋 Product Description

Oakmoore's Grade 1 Sectional Mortise Lock Set is commercial-grade hardware built for dormitories, extended-stay apartments, senior living units, and other high-traffic doors where reliability isn't optional. This is an F45 dormitory function lock with auxiliary latch. The deadbolt operates by key from outside or turn from inside, and an auxiliary dead latch automatically deadlocks the latchbolt whenever the door closes, resisting shimming beyond the standard F13 dormitory function. Operating the inside lever always retracts both bolts and unlocks the outside lever; when the deadbolt projects again, the outside lever locks, keeping the door secured until released. Certified to ANSI/BHMA A156.13 Grade 1, the industry's highest commercial rating, and UL listed for a 3-Hour fire rating (ANSI/UL 10C), this lockset meets the standards facility managers require, the same grade used across dormitories and multi-family housing. Every working part that matters is solid: a solid-cast, satin stainless steel lever and sectional rosette (2-7/16" diameter) resist corrosion, scratching, and daily wear. Inside, a 1" throw stainless deadbolt and a 3/4" throw stainless latchbolt with an anti-friction curve reduce strike wear and extend cycle life. Installation is straightforward. A 3-5/8" cylinder-to-spindle spacing and 2-3/4" backset match most commercial mortise cases, retrofitting existing prep with little modification. Field reversible for left- or right-hand doors, fitting standard 1-3/4" doors, up to 2-3/8" thick. Ships with a 6-pin Schlage-C keyway cylinder and 3 keys, keyed different as standard. Oakmoore builds commercial hardware for American businesses that need it to simply work, year after year. Every mortise lock is backed by our long-life warranty and US support, a real team stands behind the product. Grade 1 strength. Fire-rated compliance. Enhanced security for dormitory doors. Hardware you install once and stop thinking about.
