Product Description
RX9875L-NL-18 4 US4 RHR Von Duprin 98 Series Night Latch Mortise Lock Exit Device in Satin Brass
The RX9875L-NL-18 4 US4 RHR is a Von Duprin 9875 Series Mortise Lock exit device with L-18 Lever trim in Satin Brass (US4/606), sized for 4' 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.
Request to Exit — Request to Exit switch signals the access control system when the exit device is activated. 24VDC.
ANSI/BHMA A156.3 Grade 1 certified. Hex key dogging standard. Factory set RHR, field reversible.
Pro-Tip from Our Locksmiths: Mortise lock exit devices (9875) require a mortise pocket prepped into the door edge. On retrofit jobs, verify the existing mortise prep is compatible with Von Duprin's 9875 body dimensions. A Schlage L-series prep is close but not identical — don't assume cross-compatibility.
