The wide use of electrical elements and communication devices, data and voice, make wiring more and more complex and robust. Branches within electrical circuits are quite common, especially to deliver power and connectivity to certain sites. The junction boxes are used for the installation of power or communication points, preserving an aesthetic and high quality installation. The Adler universal boxes have been carefully designed to meet and cover all the current needs of the industrial and domestic sector, as they are manufactured in ABS, flame retardant and highly resistant to impact. They have the adequate and standardized size to store all the mechanisms and internal wiring necessary for the electrical installation (RETIE certified).
