Prison gates

Prison gates require high security and Industrial gate operators, the photo shows exactly this ! Model GDS 8 swing gate operators combined with GDS drive bolt locking, effectively locks gates such as these ones at a prison.

So when the gates need to open, the first thing which occurs is for the 40mm solid stainless steel ‘pin’ to retract out of the ground and then the big GDS 8 inverter drive swing gate operators swing the gates open. With the photo shown the inner gate and outer gates are interlocked, so only one gate will open at a time, thereby providing effective security.
