Lever Lockset for Commercial Doors
This heavy-duty lever lockset is built for commercial environments that require reliable mechanical access control. Its classroom function allows the outside lever to be locked or unlocked with a key while the inside lever always provides free egress. The aged bronze finish suits professional settings where durability and appearance both matter.
Fire-Rated Hardware With Grade 2 Durability
Certified to ANSI/BHMA A 156.18 and fire rated for three hours, the lockset meets life-safety requirements for commercial openings. Zinc and steel construction resists daily wear in high-traffic corridors. Normal operation remains smooth without electronic components that could fail or require power.
Fixed Backset and Door-Thickness Range
The 2-3/4 in. backset and 2-1/8 in. crossbore suit standard commercial door prep. Door thickness must fall between 1-3/8 and 1-3/4 in., so thinner residential doors or thicker specialty doors will not accept this hardware. The included 1-7/8 x 4-7/8 in. strike completes the installation for compatible frames.

Questions about this item
How do I install the Master Lock SLCICCR10B lever lockset and what step is often missed?
Fit the latch into the 2-1/8 in. crossbore, set the 2-3/4 in. backset, and secure the 1-7/8 x 4-7/8 in. strike; the step often missed is adjusting the latch bolt for the exact door thickness between 1-3/8 and 1-3/4 in.
What maintenance or replacement will this classroom-function lockset need over time?
Periodically lubricate the zinc and steel mechanism with graphite powder; replace the lever spring or cylinder if the classroom function fails to lock from the outside after heavy use.
What limit appears first on this Grade 2 lockset under sustained high-traffic use?
The ANSI/BHMA A156.18 Grade 2 cycle rating is reached before the three-hour fire rating becomes a factor in normal operation.
