Von Duprin 55EO Traditional Narrow Stile Rim Exit Device

The Von Duprin 55EO is a heavy-duty, traditional crossbar rim exit device engineered for high-traffic environments where architectural style and absolute durability must coexist. Certified to strict ANSI A156.3 Grade 1 standards and UL listed for Accident Hazard installations, this surface-mounted rim device features a classic mechanical design suited for all types of single doors, as well as double doors when paired with a central mullion.

This exit-only (EO) model is configured without an outside lever or cylinder trim, keeping the exterior face completely secure while ensuring immediate, code-compliant emergency egress from the inside. Built to accommodate historic and modern narrow-profile entries alike, its compact chassis fits exceptionally slim door stiles down to 1-3/4" (44mm). Each device comes complete with a standard 1409 strike in a dull black finish along with matching sex nuts and bolts (SNB) to accommodate standard 1-3/4" doors or thicker 2-1/4" door configurations.
