Product Description
RX99NL 4 643E Von Duprin Request to Exit (RX) 99 Series Night Latch Surface Vertical Rod Exit Device Aged Bronze
The RX99NL 4 643E is a Von Duprin 99 Series Rim exit device in Aged Bronze, sized for 4' 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.
Request to Exit — Request to Exit switch signals the access control system when the exit device is activated. 24VDC.
ANSI/BHMA A156.3 Grade 1 certified. Hex key dogging standard. Field reversible handing.
Pro-Tip from Our Locksmiths: Rim devices are visible on the door interior, so they're typically used on utilitarian doors (back exits, service doors, storage rooms) rather than customer-facing entrances. But they're reliable, affordable, and quick to install — spec them when aesthetics aren't the priority.
