To date, this is the only invisible wooden terrace fastening system of its kind to comply with the requirements FCBA (French independent testing institute) DTU 51-4 standard (French standard for the assembly of wooden terraces).
The groundbreaking concept that combines the JuAn® clips, the comfort profile of the wooden boards and the TOP LIFT positioning feet. This private deck was installed by Grad's partner Air et Soleil, as durability and sustainability were utmost important to the owners. Over time, Kebony has developed a natural silver-grey patina.
