The EL9857NL-OP-US28-3 is a Von Duprin 9857 Series Surface Three Point Latch exit device in Aluminum (US28/628), sized for 3' doors. Night Latch with Optional Pull — outside lever locks and unlocks by key with optional pull handle. 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: The 9857 three-point latch device provides three engagement points — rim latch plus top and bottom bolts. This is your go-to for high-security applications or large doors where a single latch point isn't enough to keep the door sealed. Popular on data centers and clean rooms.
