Consisting of 100 thermal boxes, 100 universal plaster covers, and 1 piece of thermal foam. The Primo thermal box THD-70, with a diameter of 60 mm, eliminates the need for complicated plastering like traditional flush-mounted boxes. The THD-70 thermal box can be installed quickly and easily in just a few seconds using the specially developed thermal foam. Thanks to the SCS connection technology, multiple thermal boxes can be lined up and securely connected - ideal for fast wiring or the installation of pre-installed devices. To ensure the box can be quickly located after plastering, it is recommended to use the universal plaster cover included in the set to protect the interior of the box. For particularly clean results, the thermal box set THDS-70-S2 is recommended, which includes a sturdy flush-mount drilling template, an integrated level, a plaster cover, and a box of thermal foam sufficient for up to 100 boxes.
