The best way to avoid any accident that could damage electrical and electronic systems is to protect them with the safest mechanisms on the market, such as the Cover for mono loudspeaker key mechanisms in aluminium of the series Simon 75. Suitable for surface and flush mounting, for its installation it is necessary to use a baseboard surface-mounted or a universal box to be recessed in the wall. This is one of the safest parts on the market, having been manufactured with materials with thermoplastic components. It is available in snow white, ivory, grey, graphite, aluminium and bronze, which increases the decorative possibilities to achieve a harmony that will stand out in the design of the installations of homes or companies. Its price, the lowest it can currently be found in the sector, makes it an affordable cover for all types of budgets.
