The Schlage ND91BD-RHO is a Grade 1 heavy-duty cylindrical lock built for high-traffic commercial openings that demand durability and security. Part of the trusted ND Series, this Vandlgard entrance/office function lock features the clean, contemporary Rhodes (RHO) lever design paired with Schlage's Vandlgard clutching mechanism to resist forced entry and vandalism. It comes prepped for a small format interchangeable core (SFIC) and ships less core, giving you the flexibility to integrate it into your existing keying system. With a standard 2-3/4" backset, a 4-7/8" strike, and a non-handed design, this lock installs quickly on most standard doors and delivers reliable everyday performance.
Features
- Grade 1 cylindrical lock certified for the most demanding commercial applications.
- Vandlgard technology allows the outside lever to rotate freely when locked, protecting the internal mechanism from abuse.
- Rhodes (RHO) lever offers a smooth, modern profile suited to a wide range of interiors.
- SFIC prep less core lets you install your own small format interchangeable core.

- Standard 2-3/4" backset with a 4-7/8" strike for broad door compatibility.
Functional Details
The ND91 entrance/office function keeps the outside lever locked or unlocked as needed, with key access from the exterior and free egress from the interior. When combined with Vandlgard, the outside lever spins freely in the locked position to absorb force and prevent damage to the lock body.
- Latchbolt operated by lever from either side except when outside lever is locked by key.
- Outside lever locked and unlocked by key.
- Inside lever always free for immediate egress.
