The QEL9857NL-OP-US15-4 is a Von Duprin 9857 Series Surface Three Point Latch exit device in Satin Nickel (US15/619), sized for 4' 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.
Quiet Electric Latch Retraction — QEL motor-driven latch retraction provides quiet, ADA-compliant remote unlocking. 24VDC power required.

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.
