The C20 wall and ceiling bend guides M20 pipes in the ideal bending radius of 30° and fixes them absolutely concrete-tight and safely with strain relief. The nail and adhesive base can be firmly connected to other grommets and bends using the plug-in system. In the in-situ concrete, the nail and adhesive base is nailed to the formwork. In the precast concrete plant, it is glued to the formwork table. Thanks to optional wings (P761), the bend can also be attached directly to the steel reinforcement. The transitions are also available in sizes M25 and M32.
