Functional Details

The L9010 is a passage function, meaning the latchbolt is retracted by the lever or knob from either side at all times, with no locking mechanism engaged. This makes it suitable for doors where controlled access is not required but a reliable latch is needed.

• Latchbolt operated by lever or knob from either side at all times.

Included Components

This item is supplied as a single lock case assembly intended to be installed into a compatible Schlage L Series mortise pocket. Levers, roses, trim, and other components are ordered separately as needed.
