Product Description
3347A-T-F-315-3 Von Duprin 3347A Series with 360T Thumbturn Fire-Rated Concealed Vertical Rod Exit Device in Black
The Von Duprin 3347A-T-F-315-3 is a touch bar concealed vertical rod exit device from the 33A Series family. Thumbturn — inside thumbturn controls the latch. Common on 33A/35A series. Ships less cylinder — order a mortise cylinder separately to match your existing keyway.
The 3347A 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 fire exit hardware — no mechanical dogging on fire-rated models. ANSI/BHMA A156.3 Grade 1 certified.
Pro-Tip from Our Locksmiths: The 3347A/3547A concealed vertical rod models hide the rods inside the door stile for a clean look. Best choice for glass storefront pairs. But concealed rods are sensitive to door sag — even 1/8 inch of sag will prevent the top rod from engaging the header strike.
