The 10th of June 2008 Copenhagen Zoo opened their brand new elephant house.  During the construction phase the architects contacted John Mast in order to gain expertise in the field of ropes. The goal was to use full lengths of ropes in a colour matching the building. The ropes were also to have a very high tensile strength (22 tons), ensuring that no hot-tempered elephants could escape. John Mast knows a lot about tensile strengths from yachting. On the seas of the world this extra strength is needed. Bottom line is that we found a piece of rope that is able to keep a hot-headed elephant detained.


After a short while the ropes was manufactured - ready to be mounted.

So now the elephants can thrive in a new top modern home, which is designed for premium conditions and in the best materials available.
