The telescopic, polycarbonate pool enclosure can be closed and opened easily and quickly, and does not require extra effort. It is equipped with a low and comfortable rail system (only 14-15 mm) that has a slip-resistant surface and can be built seamlessly, so that the open pool cover does not disturb the pool-goers. The time it takes to keep the pool clean decreases. Winterisation and the preparation for the season are greatly simplified if you use a telescopic, polycarbonate pool enclosure, since the enclosure already contributes greatly to the protection of the pool by itself.
