Mechanical lock 664 G/GF

for door

The 664 G/GF locks with deadlocking latchbolt are part of the series 600 mechanical locks for armoured doors. The 664 G/GF mechanical locks with deadlocking latchbolt maximise the security of the door and for this reason its application is recommended, for example, in the main entrance of a residential building. In this scenario, the door is normally closed by the door closer, without engaging the deadbolts, meaning that the security of the building depends solely on the efficacy of the latch. The lock can be combined with a specific electric strike, so that it is possible to open it with the individual internal intercoms of the building.
