Schlage ND91-BD-TLR Vandlgard Entrance/Office Cylindrical Lock, Tubular Lever, SFIC Prep Less Core, 2-3/4 Backset, 4-7/8 Inch Strike, Grade 1, Non Handed
The Schlage ND91BD-TLR is a Grade 1 cylindrical entrance/office lock built for high-traffic commercial openings that demand durability and security. Part of the heavy-duty ND Series, it features Vandlgard technology that allows the outside lever to rotate freely when locked, protecting the internal mechanism from forced entry and vandalism. This model comes prepped for a small format interchangeable core (SFIC) and ships less core, giving you flexibility to integrate it into an existing keying system. The clean, ergonomic TLR tubular lever pairs well with modern and traditional interiors alike, while the non-handed design simplifies installation on virtually any door.
