Knelsen GmbH specialises in the development and manufacture of window fixings for energy-efficient window systems. Our range includes not only fasteners for windows in the reveal and in front of the façade, but also window sill brackets, mounting aids and fastening systems in roller shutter boxes.

We are characterised by our practice-oriented customer advice, a wide range of products and their pragmatic use. The constant further development of these products and our company is also particularly important to us. In addition to our headquarters in Salzkotten, we now have further locations in Poland, Russia and, since 2021, a branch in Belgium.
