The adjustable box for concrete floor installation from the Simon K45 series, with graphite finish, designed for 6 elements, also allows raised floor installation for greater product versatility. For maximum safety, this product is manufactured with halogen-free thermoplastic materials to guarantee there is no flame propagation and smoke toxicity in case of fire. This version of adjustable box, in graphite for six elements, can withstand temperatures between -5 °C and 60 °C and has a maximum temperature of 90 °C. Keep in mind that once the installation is complete, it must be combined with the complementary plastic tray (Art. No. 52052103-035). Additionally, the collection of adjustable boxes from Simon K45 offers you the option of adding a flush-mount trim cover, in case it is not installed in a floor with the same finish.
