Product Description
QEL99NL-OP-US28-4 Von Duprin 99 Series with 110MD/WD Night Latch Rim Exit Device with Quiet Electric Latch Retraction in Anodized Aluminum
The QEL99NL-OP-US28-4 is a Von Duprin 99 Series Rim exit device in Aluminum (US28/628), sized for 4' doors. Night Latch with Optional Pull — outside lever locks and unlocks by key with optional pull handle. 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. 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.
