Von Duprin 9947EOF26D3 Concealed Vertical Rod Exit Device

Product Description

The VON DUPRIN 9947EOF26D3 is a fire-rated concealed vertical rod exit device designed for single-door commercial applications requiring compliant emergency egress hardware. Built with a grooved case profile, it conceals the vertical rod mechanism within the door for a clean installation. The 626 Satin Chrome finish provides corrosion resistance suited to high-traffic public and institutional environments. At 36.75 inches in length, this unit fits standard 3-foot door preparations. Licensed locksmiths, door hardware specialists, and commercial contractors typically specify and install this device on rated door assemblies.

This exit device is intended for commercial and institutional buildings where fire-rated egress hardware is required by code. Typical applications include corridors, stairwells, and exit passageways in schools, hospitals, government facilities, and office buildings. The concealed vertical rod design suits applications where exposed rods are not acceptable for aesthetic or operational reasons. The EOF designation indicates an end-of-run frame configuration, which is relevant when specifying the device for specific frame and door preparations.
