Von Duprin 9827EOF26D4 Surface Vertical Rod Exit Device

Product Description

The VON DUPRIN 9827EOF26D4 is a fire-rated surface vertical rod exit device designed for use on 4-foot wide door openings in commercial and institutional buildings. This device mounts to the door surface and uses vertical rods to engage latches at the top and bottom of the door frame, providing compliant panic hardware for egress applications. The 626 satin chrome finish provides corrosion resistance suited to high-traffic interior environments. Weighing 19 pounds, this unit is a robust, full-length device intended for professional installation by licensed door hardware or general contractors working to applicable fire and life safety codes.

The 9827EOF26D4 is used on fire-rated door assemblies in commercial, institutional, and public occupancy buildings where code-compliant exit hardware is required. Typical installations include stairwell doors, corridor doors, and main egress doors in schools, hospitals, offices, and government facilities. The surface vertical rod configuration is appropriate for doors where concealed vertical rods are not feasible or where retrofitting an existing frame. The EOF (end of frame) configuration addresses specific frame conditions at the latch side of the door.

Installation Notes

Installation should be performed by a licensed door hardware technician or qualified contractor familiar with NFPA 80 fire door assembly requirements and applicable local building codes. Before installation or service, ensure the door assembly is de-latched and that any connected access control or alarm wiring is de-energized per the system documentation. Verify that the door frame and door construction are rated to match the fire rating of this exit device. Do not modify the vertical rod length or latch engagement depth beyond manufacturer-specified adjustment ranges.
