Product Description

The 9848NL-US28-4 is a Von Duprin 9848 Series Concealed Vertical Rod 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 troubleshooting a 9847/9848 that won't latch, check the top bolt first. Concealed rod devices rely on precise alignment of internal components, and building settling can throw off the top bolt engagement. A simple strike adjustment often fixes what looks like a device failure.
