Product Description
RX78NL-F-US10-3 Von Duprin Fire Rated 78 Series Request to Exit Night Latch Rim Exit Device in Satin Bronze
The Von Duprin RX78NL-F-US10-3 is a crossbar rim exit device for storefront and aluminum 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.
The 78 Series crossbar provides a wide activation zone across the full width of the door — maximum push area for emergency egress. Available in 3-foot width. Non-handed design works for both LHR and RHR door swings. UL listed for fire exit hardware — no mechanical dogging on fire-rated models. ANSI/BHMA A156.3 Grade 1 certified.
Pro-Tip from Our Locksmiths: The 78 crossbar is non-handed — same device works for LHR and RHR swings. That's a major advantage over the 55 Series narrow stile which is factory-handed. If you're not sure about handing at order time, the 78 takes the guesswork out.
