Product Description
LD9957DT-US4-4 Von Duprin 9957 Series Dummy Trim Surface Three Point Latch Device with Less Dogging in Satin Brass
The LD9957DT-US4-4 is a Von Duprin 9957 Series Surface Three Point Latch exit device in Satin Brass (US4/606), sized for 4' doors. Dummy Trim — non-functional outside pull for appearance. Provides a handle on the outside without any latch control. No cylinder required for this function.
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.
