Product Description
RX9975L-NL-05-F 4 26D RHR Von Duprin 99 Series Night Latch Fire Rated Mortise Lock Exit Device in Satin Chrome
The RX9975L-NL-05-F 4 26D RHR is a Von Duprin 9975 Series Mortise Lock exit device with L-05 Lever trim in Satin Chrome (US26D/626), 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.
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: Mortise lock exit devices (9975) require a mortise pocket prepped into the door edge. On retrofit jobs, verify the existing mortise prep is compatible with Von Duprin's 9975 body dimensions. A Schlage L-series prep is close but not identical — don't assume cross-compatibility.
