Product Description
78NL-OP-413-4 Von Duprin 78 Series with 110MD/WD Night Latch Rim Exit Device in Duranodic Dark Bronze
The Von Duprin 78NL-OP-413-4 is a crossbar rim exit device for storefront and aluminum 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.
The 78 Series crossbar provides a wide activation zone across the full width of the door — maximum push area for emergency egress. Available in 4-foot width. Non-handed design works for both LHR and RHR door swings. UL listed for panic exit hardware with hex key dogging standard. 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.
