Product Description

The LD9948NL-US4-3 is a Von Duprin 99 Series Rim exit device in Satin Brass (US4/606), 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.
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. 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.
