The function of the clamps is the alignment of the piping and its fixation. They are used to guarantee a practical, quick and safe installation of piping, varying in horizontal and vertical positions. Minimum use, depending on the size of the chimney, is recommended for one clamp every 1.5 meters.
You should choose the model that best suits the installation in question. You should keep in mind that in the vertical section the support ensures greater sustainability of the chimney.
Works with M8 threaded rod (not included).
