The 9957NL-OP-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 with Optional Pull — outside lever locks and unlocks by key with optional pull handle. Inside always free for egress.

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.
