It has always been Berliners aim to create sophisticated products under the main constraints of design and safety, without compromising function and stability. Hence, in early 2002 Berliner introduced a new tensioning mechanism the AstemTT. After a successful trial period Berliner have adopted this rope tensioning technology as the standard across the entire Univers Net structures range.

Aside from the intelligent mechanism and harmonious integration into the Frameworx structure, AstemTT simplifies installation. The spatial net can be tensioned evenly across the entire structure. Furthermore, all tensioning mechanisms are contained within closed spheres, making them inaccessible for users.
