Von Duprin Concealed Vertical Rod Exit Devices

Key Features

• Concealed vertical rod mechanism with top and bottom latching provides two‑point security while keeping rods hidden inside the door.
• Heavy‑duty Grade 1 construction engineered for demanding, high‑cycle applications on 3' and 4' door widths.
• Non‑handed or field‑reversible designs (depending on series) simplify stocking and installation on left‑ or right‑hand reverse doors.
• Fire‑rated models available with no dogging to maintain positive latching on labeled doors, suitable for stair, corridor, and cross‑corridor openings.
• Multiple series options (such as 33/35A, 98/99) to match wide‑stile applications, electric latch retraction, and other electrified options when needed.
• Architectural finishes include aluminum, dark bronze, and stainless‑tone options to coordinate with frames, hardware, and trim.

Key Benefits

• Enhanced security and door control: Two‑point latching at the head and sill improves resistance to forced entry and keeps tall doors stable under load.
• Clean aesthetics: Concealed rods and compact latches maintain a streamlined look, especially important on high‑visibility doors and glass‑lite openings.
• Code‑compliant egress: Single‑motion operation via the push bar meets panic hardware requirements for life‑safety doors in high‑occupancy buildings.
• Reduced tampering and damage: Hidden rods are protected inside the door, decreasing exposure to abuse, carts, and vandalism.
• Flexible application: Fire‑rated and non‑rated versions, multiple bar widths, and trim combinations allow one product family to cover many opening types.

Applications

• Schools and universities: Pairs of corridor doors, auditorium entries, and gym doors where concealed hardware and strong latching are needed.
• Healthcare and hospitals: Patient corridor and cross‑corridor doors requiring clean looks, quiet operation, and reliable egress.
• Commercial offices and government buildings: Lobby, stair, and interior fire doors where appearance and performance both matter.
• Retail and mixed‑use facilities: Back‑of‑house and public entries on tall or paired doors that need secure, smooth‑operating CVR exit devices.
