PREMIUM QUALITY MATERIAL: It is punched and molded from high quality engineering grade ABS flame retardant materials. The average thickness of the box body is relatively high and it has strong impact resistance. It also has strong flame retardancy and good insulation, and can prevent static electricity. .ADVANTAGES: The junction box is dustproof and waterproof, and the protection level is IP65. Good sealing performance effectively block water droplets and water vapor from outside. Even if installed on deck and subjected to the impact of sea waves, the internal components will not be damaged. .PROFESSIONAL DESIGN: The junction box adopts a type of inner screw nut, which can better fix the guide rail terminal box and the junction board. The junction box uses professional stainless steel screws and full copper nuts, which makes the installation more stable and longer service life. .OPENINGS: There are several openings on the outside of the junction box. You can use waterproof connectors, wiring terminals, mounting plates, etc. to meet all needs. .WIDE APPLICATION: Watertight and dustproof junction boxes are often used in various installations such as electrical, electronic, communication, control panels, terminal blocks, printed circuit boxes, ships, coastal factories and docks. . .
