Product Description
9975L-NL-06-F 3 315 RHR Von Duprin 99 Series Night Latch Fire Rated Mortise Lock Exit Device in Black
The 9975L-NL-06-F 3 315 RHR is a Von Duprin 9975 Series Mortise Lock exit device with L-06 Lever trim in Black (315/315), sized for 3' 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.
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.
