Sargent 12-8873-F-ETB-12V Electrified Fire Rated Rim Exit Device, Fail Safe Power Off Unlocks Lever, For 33-36 Inch Width Door, Less Dogging

The Sargent 12-8873-F-ETB-12V is a heavy-duty electrified rim exit device built for fire-rated openings that demand reliable, controlled access. Designed for doors measuring 33 to 36 inches wide, this Grade 1 device pairs a fire-rated rim exit mechanism with the ETB lever trim for secure outside operation. Operating on 12V DC, it uses a fail-safe configuration, meaning the lever unlocks whenever power is removed—ideal for life-safety and egress applications. Free egress is always available from the inside. Supplied less dogging to maintain fire-rated integrity, it offers dependable performance for commercial entrances, stairwells, and secured corridors where code compliance and durability are essential.
