The LD9957NL-313-3 is a Von Duprin 9957 Series Surface Three Point Latch exit device in Dark Bronze (313/313), sized for 3' 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.
Latch Detector — Latch Detector monitors door position — reports latch bolt status to the access control panel. 24VDC.
ANSI/BHMA A156.3 Grade 1 certified. Hex key dogging standard. Field reversible handing.
Pro-Tip from Our Locksmiths: The 9957 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.
