Schlage L9480J Storeroom Mortise Lock with Deadbolt, 17 Lever, N Escutcheon, FSIC Less Core, Satin Chrome 626

A storeroom door has to stay locked from the corridor every time it closes, yet the person inside must never be trapped. The Schlage L9480J from the Schlage L series handles that job as a mortise lock with an added deadbolt: the outside 17 lever is always fixed, so entry from that side takes a key, while the inside lever is always free. One turn of the inside lever retracts both the latchbolt and the deadbolt at once.

From outside, the key retracts the latchbolt and throws the deadbolt; inside, a thumbturn throws the bolt. An auxiliary latch deadlocks the latchbolt when the door is locked. The deadbolt carries an anti-saw pin against cut-through, a security blocking hub keeps the lock from being reached by pulling the levers, and a breakaway spindle holds the door secured if the lever is attacked. The latchbolt has a two-piece anti-friction tongue to reduce wear and reverses in the field without opening the case.

The lock takes a full-size interchangeable core (FSIC) and comes less core, so you fit the 6-pin core of your own key system. The finish is satin chrome, BHMA 626 (US26D), on a brass or bronze base, with an N escutcheon. The maker states Grade 1, a 3-hour (180 min) fire rating for Class A labeled doors and BAA qualification. Schlage backs it with a 3-year limited warranty.
