Von Duprin 9975EOF26D3 Mortise Exit Device 626 Chrome

Product Description

The VON DUPRIN 9975EOF26D3 is a 3-foot fire rated mortise exit device with a grooved case and 626 satin chrome finish, designed for commercial door hardware applications in public buildings, schools, hospitals, and institutional facilities. The mortise-style configuration integrates directly with a mortise lock body for a streamlined installation. The end-of-field (EOF) designation indicates field-configurable options, giving installers flexibility at the job site. This device is sold as a single unit and is intended for installation by a licensed door hardware specialist or commercial locksmith.

This exit device is suited for commercial and institutional buildings requiring fire-rated egress hardware on interior or exterior corridor doors. The 3-foot (39.8-inch) case length is appropriate for standard 3-foot door openings. The grooved case styling is commonly specified in retrofit and new-construction projects where a clean, commercial-grade aesthetic is required alongside life-safety compliance. Facilities managers and commercial door hardware contractors are the primary installers of this type of device.

Installation Notes

Installation should be performed by a licensed door hardware professional or commercial locksmith familiar with NFPA 80 fire door assembly requirements and local building codes. Power down any electrified hardware connected to the door assembly before beginning work. Verify that the door, frame, and lock body are compatible with a mortise-style exit device before installation. Do not modify the fire label or door assembly in any way that would void the fire rating.
