Von Duprin 9875EOF26D4 Mortise Exit Device Fire Rated

Product Description

The VON DUPRIN 9875EOF26D4 is a fire-rated mortise exit device designed for commercial door applications requiring code-compliant panic hardware. Built with a smooth case profile, this unit operates with a mortise-style latch mechanism and ships in a 626 satin chrome finish. At 48.75 inches in length and 17 pounds, it is a substantial piece of hardware suited for high-traffic egress points. Licensed locksmiths, commercial door hardware installers, and security contractors are the typical trades responsible for specifying and installing this device.

This exit device is intended for use on commercial and institutional buildings where fire-rated egress hardware is required by local building and life-safety codes. Typical installations include corridor doors, stairwell egress doors, and other openings that must meet fire door assembly requirements. The smooth case design keeps the profile clean for applications where aesthetics matter alongside compliance. The 626 satin chrome finish coordinates with standard commercial door hardware in office, healthcare, education, and government facilities.

De-energize any connected access control or electric latch retraction wiring before beginning work. Confirm fire label integrity on both the door and the device after installation is complete.
