Product Description
LD99L-NL-18 4 US4 RHR Von Duprin 99 Series Night Latch Rim Exit Device in Satin Brass
The LD99L-NL-18 4 US4 RHR is a Von Duprin 99 Series Rim exit device with L-18 Lever trim in Satin Brass (US4/606), 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.
Latch Detector — Latch Detector monitors door position — reports latch bolt status to the access control panel. 24VDC.
ANSI/BHMA A156.3 Grade 1 certified. Hex key dogging standard. Factory set RHR, field reversible.
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.
