Product Description
CXA99L-NL-03-F 3 4 LHR Von Duprin Fire Rated Motorized Latch (CXA) 99 Series Lever Night Latch Surface Vertical Rod Exit Device 4
The CXA99L-NL-03-F 3 4 LHR is a Von Duprin 99 Series Rim exit device in 4, 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.
Chexit Alarm — Chexit delayed egress alarm — provides a 15-second delay with audible alarm before allowing exit. 24VDC.
Fire Rated — UL listed for use on fire-rated openings. Mechanical dogging is deleted per UL code on fire-rated models. 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.
