Schlage ND91-JD-LON Vandlgard Entrance/Office Cylindrical Lock, Longitude Lever, Schlage FSIC Full Size Interchangeble Core, Less Core, 2-3/4 Backset, 4-7/8 Inch Strike, Grade 1, Non Handed
The Schlage ND91JD-LON is a Grade 1 heavy-duty cylindrical lock built for demanding commercial openings that require secure entrance and office functionality. As part of the trusted ND Series, it features Schlage's Vandlgard design, which allows the outside lever to rotate freely when locked to help prevent damage from forced entry or vandalism. This model comes with the Longitude (LON) lever and is prepped for a Schlage Full Size Interchangeable Core (FSIC), shipped less core so you can key it to your existing system. With a 2-3/4 inch backset, non-handed installation, and durable ANSI-rated construction, it delivers dependable performance for schools, offices, and high-traffic buildings.
Features
- Vandlgard function protects the lock by allowing the outside lever to rotate freely when in the locked position.
- Entrance/office function provides flexible access control for commercial spaces.
- Longitude (LON) lever design offers a clean, modern appearance.
- Accepts a Schlage FSIC full size interchangeable core (sold separately, shipped less core).
- Grade 1 rated for the highest level of commercial durability.
- Non-handed design simplifies ordering and installation.
Functional Details
The ND91 Entrance/Office function is designed for spaces where the door may be locked or unlocked as needed. Vandlgard technology reduces the risk of lock damage by letting the outside lever spin freely when locked, rather than resisting force.
- Latchbolt operated by lever from either side except when outside is locked by key or turn/push button.
- Turn/push button locking: pushing and turning button provides lockout, requires turning button to unlock.
- Push button locking: pushing button locks outside lever, unlocked by key outside or by rotating inside lever.
- Auxiliary latch deadlocks latchbolt when door is closed.
Included Components
This lock ships with the LON lever trim, latch, and strike. A Schlage FSIC core must be ordered separately to complete the keying.
