Very easy installation - no drilling required

The bar looks very valuable out in nice shiny crystal white. The installation is very simple: pull apart rod on the wall to the desired length, but so that you can take it away again, then about 1 cm (again look at the package, I do not remember exactly) pull further and both rod parts against each turn in order to fix it. Now tension between both walls, while the shorter rod part push slightly inwards and release it at the desired position - holds. Could not be simpler.
