CircleLock Combi - high security connection portal

With all of the security features of a high security portal, the Circlelock Combi is a retrofit option for companies looking to upgrade their security level, while saving on both space and renovation costs and having the additional protection of a fire / smoke / airtight-rated door. The interlocking half portal attaches to an existing swing door, transforming an ordinary door into a high security entrance, capable of protecting the most sensitive areas from unauthorised entry and piggybacking.
