Product Description
98NL-US28-4 Von Duprin 98 Series with 990NL Night Latch Rim Panic Exit Device in Anodized Aluminum
The 98NL-US28-4 is a Von Duprin 98 Series rim exit device in Aluminum (US28/628), 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.
ANSI/BHMA A156.3 Grade 1 certified. Hex key dogging standard. Field reversible handing.
Pro-Tip from Our Locksmiths: When quoting 98 rim devices, check the frame for strike compatibility. The 98 uses a standard rim strike, but on hollow metal frames you may need a longer lip strike if the frame rabbet is deeper than standard. Most callbacks on rim devices are strike alignment — get it right at install.
