Principle began by undertaking an extensive testing programme in which test samples were subject to sustained and prolonged attacks. Then they installed their patented, aesthetically pleasing counters, partitions and doors with extreme attack resistant features including extra deep glazing, steel reinforcement, concealed fixings and mechanical deadlocks. This provided the safety and peace of mind needed whilst also ensuring that if threat levels increased, they could be adapted to suit.

It's not just being safe that matters, its feeling safe.
