Sargent 12-8974-F-ETB-24V Fire Rated Mortise Exit Device, Electrified Trim 24V Fail Secure, ET Control, B Lever, For 33-36" Width Door, Less Dogging, No Cylinder, Grade 1

The Sargent 12-8974-F-ETB-24V is a Grade 1 fire rated mortise exit device built for heavy-duty commercial openings measuring 33 to 36 inches wide. It features 24-volt electrified ETB trim configured for fail secure operation, meaning the outside lever remains locked until power is applied, providing reliable access control for secured entrances. The ET trim design pairs with the B lever for a clean, durable aesthetic, while the fire rated construction makes it suitable for labeled door assemblies where positive latching is required. No Cylinder: this configuration has no cylinder override and does not require an override cylinder.
