Schlage ND91-BD-OME Vandlgard Entrance/Office Cylindrical Lock, Omega Lever, SFIC Prep Less Core, 2-3/4 Backset, 4-7/8 Inch Strike, Grade 1, Non Handed
The Schlage ND91BD-OME Vandlgard Entrance/Office Cylindrical Lock combines Grade 1 durability with the security features commercial buildings demand. Built as part of Schlage's rugged ND Series, this lock is engineered for high-traffic openings where reliability matters most. It features the Vandlgard clutch mechanism, allowing the Omega (OME) lever to rotate freely when locked to resist forced entry and vandalism. Prepped for a small format interchangeable core (SFIC) but shipped less core, it offers flexibility for facilities that manage their own keying systems. With a 2-3/4 inch backset and non-handed design, installation is straightforward for a wide range of standard door applications.
Features
- Vandlgard clutch design lets the lever rotate freely in the locked position to protect against vandalism and forced entry.
- Entrance/Office function provides versatile locking control for offices, entryways, and interior rooms.
- Prepped for small format interchangeable core (SFIC), shipped less core for easy integration into existing keying systems.
- Omega (OME) lever delivers a clean, contemporary profile suited to modern commercial interiors.
- Non-handed construction simplifies stocking and installation for either door orientation.
- Grade 1 rated for heavy-duty commercial performance and long service life.
Functional Details
The ND91 Entrance/Office function allows the door to be locked or unlocked using a key from the outside, while the inside lever always provides free egress. The Vandlgard mechanism disengages the outside lever when locked so it spins freely, preventing damage from attempted force.
- Latchbolt operated by lever from either side except when outside is locked by key.
- Locking or unlocking the outside lever is controlled by key in the outside lever.
- Inside lever always free for immediate egress.
