The Von Duprin 3347AEO-F-3 Fire Rated Concealed Vertical Rod Exit Device is a heavy-duty, Grade 1 panic exit solution designed for code-compliant egress on commercial fire-rated doors. Engineered for 28"–36" wide, 84" high hollow metal or approved fire-rated wood doors, this exit-only device features a concealed vertical rod design with a narrow stile pushpad for a clean, low-profile appearance. UL 305 listed and ANSI/BHMA A156.3 certified, it delivers reliable top and bottom latching without dogging, meeting fire-door requirements while ensuring fast, safe exit in emergency situations. The non-handed design simplifies installation on single or double doors, while the grooved mechanism case with a one-piece center cover provides long-term durability for high-traffic commercial environments.
