effeff - ASSA ABLOY Electric strike 331U80------F94

The 331U80 escape door strike is specifically designed for use in locking doors along escape routes. As an additional locking device, our model 331U80 is also suitable for applications in fire doors. Due to the safe unlocking under preload (max. 5000 N), this is mainly used on doors with escape route requirements. In airlock systems, sound insulated doors and doors where pressure on the strike latch is to be expected due to the design, the 331U series ensures safe operation.
