Product Description
99NL 3 643E Von Duprin 99 Series Night Latch Surface Vertical Rod Exit Device Aged Bronze
The 99NL 3 643E is a Von Duprin 99 Series Rim exit device in Aged Bronze, sized for 3' doors. Night Latch — outside lever locks and unlocks by key, inside always free for egress. Ships less cylinder — order a mortise cylinder separately to match your existing keyway.
ANSI/BHMA A156.3 Grade 1 certified. Hex key dogging standard. Field reversible handing.
Pro-Tip from Our Locksmiths: Rim exit devices mount on the surface of the door without requiring mortise or internal routing. The 99 series rim devices are the easiest to install on retrofit jobs where door prep is limited. Great for quick code compliance upgrades on existing doors.
