Product Description
QEL9947L-NL-17 4 US3 LHR Von Duprin 99 Series Night Latch Concealed Vertical Rod Exit Device in Bright Brass
The QEL9947L-NL-17 4 US3 LHR is a Von Duprin 9947 Series Concealed Vertical Rod exit device with L-17 Lever trim in Bright Brass (US3/605), 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.
Quiet Electric Latch Retraction — QEL motor-driven latch retraction provides quiet, ADA-compliant remote unlocking. 24VDC power required.
ANSI/BHMA A156.3 Grade 1 certified. Hex key dogging standard. Factory set LHR, field reversible.
Pro-Tip from Our Locksmiths: Concealed vertical rod devices (9947/9947WDC) hide the rods inside the door — cleaner look than surface rods. Trade-off: you need a prepped door with internal routing. On retrofit jobs, verify the door has CVR prep before quoting. If it doesn't, you're looking at field prep or a door swap.
