Schlage ND91-JD-SPA Vandlgard Entrance/Office Cylindrical Lock, Sparta 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-SPA is a Grade 1 Vandlgard entrance/office cylindrical lock built for demanding commercial environments where durability matters. Part of Schlage's heavy-duty ND Series, this lever features the clean, contemporary Sparta (SPA) design and accepts a Schlage FSIC full-size interchangeable core, shipped less core so you can key it to your existing system. The Vandlgard feature protects the lockset against forced rotation by allowing the lever to move freely without retracting the latch, preventing damage during attempted vandalism. With a 2-3/4 inch backset and a 4-7/8 inch strike, it installs into standard commercial door preparations and is non-handed for straightforward field installation.

Functional Details

- Rotating turn-button locks or unlocks outside lever.
- Closing door does not release turn-button.
