The box is designed for concrete floors. After hardening of the concrete mixture, the floor box KOPOBOX is installed. The package includes a cover plate to prevent the box from being poured over with concrete. The minimum height of the concrete layer is 57 mm, maximum 75 mm. The desired height of the box is adjusted by raising the internal insert using screws in the corners of the box. With a SN-leveling set, it is possible to increase the height for concreting by up to 35 mm. The box is designed for wiring pipes and PUK floor canal.
