Model range 331U
Escape Door Strike 331U80 is especially designed to lock doors along escape routes. Our Model 331U80 is also suitable as an additional locking device for fire doors. Thanks to its reliable unlocking under pre-load (max. 5,000 N), it is primarily used in doors which are subject to escape route requirements. The 331U Model Series is guaranteed to work reliably in interlock systems, on soundproof doors and on doors where pressure is expected to act on the electric strike latch due to the structural design.
