Product Description
QEL99L-17-F 4 643E LHR Von Duprin 99 Series Classroom Fire Rated Rim Exit Device in Aged Bronze
The QEL99L-17-F 4 643E LHR is a Von Duprin 99 Series Rim exit device with L-17 Lever trim in Aged Bronze, sized for 4' doors. Classroom Function — outside lever is locked until unlocked by key, relocks automatically when door closes. 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.
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.
