The Sargent 12-8875-F-ETB-24V is a fire rated rim exit device built for demanding commercial openings that require reliable life-safety performance and electrified access control. Part of Sargent's 80 Series, this unit pairs a rim-mounted latch with electrified ETB lever trim operating on 24 volts. Configured for fail safe operation, the trim unlocks when power is removed, making it well suited for applications where free egress and controlled re-entry are essential during a power loss. Designed for doors measuring 33 to 36 inches in width, it comes less dogging as required for fire rated installations and delivers the durability expected from Sargent hardware.
