This Simon K45 adjustable floor box has capacity for a total of 8 elements. Its highly resistant materials are metal and have the advantages of halogen-free, self-extinguishing thermoplastic. Therefore, this product's safety is guaranteed, as it is able to resist higher than normal temperatures. In the event of fire, the thermoplastic materials contribute to the prevention of flame propagation and the reduction of smoke. Its installation is very simple, and only needs to be completed with a plastic tray (Art. No. 52052104-035). It is designed for recessed installation in a concrete floor, although it may also be installed in a raised floor. If it is not installed in a concrete floor with the same finish, a good option is to use a flush-mount trim cover (Art. No. 52053104-035), which will integrate the product perfectly into the floor.
