Knall - Shop Online - Made To Measure

The method of installing our products is divided into two main categories: Standard (invasive) and non-invasive:

Standard installation

Non-invasive installation

The option of non-invasive installation affects the final price of the product, due to the use of a special bottom bar - an element also common for the version designed for roof installation - and the necessity of using additional mounting brackets.
