Sargent 12-8875-G-ETB-12V Electrified Fire Rated Rim Exit Device, Fail Safe Power Off Unlocks Lever, Key Retracts Latch, For 43-48 Inch Width Door, Less Dogging — Core Options: KD LA keyway keyed differently with 2 change keys; or LC Less Cylinder (Option)

The Sargent 12-8875-G-ETB-12V is a fire rated rim exit device built for wide openings measuring 43 to 48 inches. It pairs the durable 8800 series exit mechanism with the electrified ETB (G trim design) lever, operating on 12V DC in a fail safe configuration—power loss unlocks the outside lever for immediate egress and access during emergencies. The key-retractable latch provides reliable control, while the less dogging design maintains the device's fire rating by keeping the latch active at all times. This combination makes it a dependable choice for institutional, commercial, and access-controlled fire door applications where security and life safety must work together.
