L Series Commercial Grade 1 Mortise Keyed Entry Single Cylinder Entrance Lock Door Lever Set

The safety of your buildings is something Schlage takes very seriously. That's why every Schlage lock and deadbolt undergoes intensive testing to determine its ANSI grade level; including cycle; resistance; door impact; warped door and bolt strength tests. Every one of Schlage's L-Series locks meets ANSI Grade 1 standards for safety.

Office and Inner Entry Lock: The latchbolt is retracted by the lever from either side when unlocked. When locked; the latchbolt is retracted by use of a key outside; or by a turn of the lever inside. Lock is engaged by use of a key from the outside or by the thumbturn from the inside. The outside lever remains locked until thumbturn is returned to vertical or lock is unlocked by key. The auxiliary latch deadlocks the latchbolt when door is closed. The inside lever is always free for immediate egress.

Schlage L-Series Extra Heavy Duty Mortise Locks are built to withstand the rigors of daily use without fail. Schlage's L9000 Series locks are ideal for use in schools; hospitals and factories; where the finest hardware must also deliver consistent; dependable operation and stand up to constant use and abuse.
