Two-component fire-resistant junction boxes combine reliability and high installation speed. They are used when laying fire safety systems on various surfaces of buildings and structures, are necessary for the mechanical protection of wire and cable connection points, as well as for protection against the penetration of dust, moisture, and foreign objects. A concise design contributes to the aesthetic installation of wiring, and membranes allow for increased installation speed (compared to the speed when using junction boxes with cable glands). The material of the boxes is halogen-free, which allows the product to be used in public places with high concentrations of people. The box has a monolithic design with a seal and membranes, achieving a high IP66 protection rating.
