Electric Releases for Deadlocks

All Westminster electric deadlock releases are suitable for high security applications. The 984 provides controlled access into Prisons, Cells, Custody Suites and Police Stations.

The 957 and 942 are ideal where the customer needs electric unlocking of deadlocks, without the worry of handle overrides from the secure side.
