Schlage ND91-BD-SPA Vandlgard Entrance/Office Cylindrical Lock, Sparta Lever, SFIC Prep Less Core, 2 3/4 Backset, 4 7/8" Strike, Grade 1, Non Handed

The Schlage ND91BD-SPA is a Grade 1 cylindrical lock built for high-traffic commercial openings that demand strength and reliability. As part of Schlage's proven ND Series, it features Vandlgard technology, which allows the outside lever to rotate freely when locked, protecting the internal mechanism against forced entry and vandalism. This entrance/office function lock ships prepped for a small format interchangeable core (SFIC) but less core, giving facility managers flexibility to add their preferred keying system. Paired with the clean, contemporary Sparta (SPA) lever and a non-handed design, it installs easily on virtually any door and delivers dependable performance in schools, offices, and institutional environments.
