Product Description
8875NL-F-SPBLK-RHR Von Duprin 8875 Series with 880NL-M Night Latch Fire Rated Mortise Lock Device in Black
The Von Duprin 8875NL-F-SPBLK-RHR is a narrow stile mortise lock exit device that combines the 88 Series pushpad with a heavy-duty mortise lock body for maximum latch strength. 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 8875 pairs the slim pushpad activation with mortise-grade latching — a step up from rim devices when the door sees heavy traffic or requires the security of a mortise lockset. Requires full mortise pocket prep. This is a handed device — verify LHR or RHR before ordering. 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 8875 is always handed and available in keyed functions (L, NL, TP, K). When ordering with lever trim, the lever sits on the outside and operates the mortise lock body directly — it's not just a pull handle like on the rim device.
