The end and transition sleeve C-20 leads M20 pipes further and fixes them absolutely concrete-tight and safely with no strain. The nail and adhesive base can be firmly connected to other sleeves 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, M32 and M40.
