Eff Eff 351M Motorised lock case

Eff Eff 351M.80 Motorised Electric Swing Door Strike

The Eff Eff 351M.80 is a premium motorised electric strike engineered for swing, double swing, and carousel doors where quiet, reliable locking is essential. Using an innovative electric motor drive rather than a solenoid, the 351M.80 is virtually silent during operation - resolving the noise complaints that are common with solenoid-type strikes in office, hotel, or residential environments. Operating on 12VÑ48V DC, with a 5,000N holding force and integrated monitoring and armature contacts, it provides secure locking with real-time status feedback. Suitable as a supplementary locking system on fire doors (BS476), universally handed, and compatible with the 351U. If you're specifying access control for a swing door where noise and compliance are both concerns, the 351M is the solution.
