Applications

The Sargent 68-3079 Rail Assembly is the correct replacement part for facilities maintaining Sargent 80 Series exit devices on doors in the 43- to 48-inch width range. Typical applications include commercial office buildings, schools, hospitals, government facilities, and industrial buildings where the 80 Series panic hardware is already installed.
