Product Description
EL9857NL-US28-4 Von Duprin 9857 Series with 990NL Night Latch Surface Three Point Latch Device with Electric Latch in Anodized Aluminum
The EL9857NL-US28-4 is a Von Duprin 9857 Series Surface Three Point Latch 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 servicing a 9857 three-point latch, check all three latch points independently. A misaligned top or bottom bolt can cause the whole device to bind. Adjust strikes one at a time, starting with the rim latch, then top, then bottom.
