This device is designed to make the installation of pipes in underfloor heating systems much easier and quicker. The product is reusable and can be reused. The swivel bracket considerably reduces and simplifies all work as it is fixed to the fittings using locks. Their design allows the clip to be securely fastened to the reinforcement mesh to be laid. And in the event of incorrect installation, the swivel bracket can be removed and reattached. Special locks hold the trunking securely in the grooves. At the same time, they are flexible enough to reduce the likelihood of the heat line rubbing against the clamp or fittings. In winter, the clamp expands along with the pipe. As a result, the products practically do not rub against each other, which reduces the likelihood of damage.
