Product Description
3547A-NL-LHR-US26D-3 Von Duprin 3547A Series with 386NL Night Latch Concealed Vertical Rod Exit Device in Satin Chrome
The Von Duprin 3547A-NL-LHR-US26D-3 is a touch bar concealed vertical rod exit device from the 35A Series family. 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.
The 3547A concealed vertical rod design hides the rods inside the door stile for a clean look. Latches at the header and threshold for positive latching on pairs of doors. Available in 3-foot width. UL listed for panic exit hardware with hex key dogging standard. ANSI/BHMA A156.3 Grade 1 certified.
Pro-Tip from Our Locksmiths: Concealed vertical rod devices on fire-rated doors must have positive latching at both the top and bottom. That means the top rod MUST reach the header strike with enough force to fully engage. If the door is sagging, fix the hinges first.
