Junction box 115×64×46 with cover and metal clip C20

The 115x64x46 Connection Box with Cover and Metal Clamp C20 is a technical element designed to be embedded in plasterboard or drywall partitions, offering a compact, secure, and durable solution for the distribution and protection of electrical splices or low-voltage connections. Its fastening system with metal clamps and closing cover ensures a professional installation and easy maintenance, adapting to modern electrical projects with high quality and reliability requirements.

Technical Design and Materials

Manufactured from high-strength technical ABS, the C20 box combines structural rigidity, electrical insulation, and lightness. This self-extinguishing, halogen-free material offers excellent performance against temperature, impacts, and prolonged exposure to moisture. Its black finish enhances durability and conceals possible installation marks, while the removable white cover allows quick access to the interior without compromising the seal. The assembly guarantees a long service life and reliable protection for any type of embedded installation.

Metal Clamp Fastening System

The C20’s fastening system uses galvanised metal clamps that ensure a firm grip on plaster panels, preventing displacement or looseness over time. These clamps, operated by front screws, expand against the partition when tightened, providing a stable hold without the need for adhesives or additional elements. This system also allows easy removal of the box for maintenance without damaging the drywall or compromising the mounting structure.

Capacity and Functionality

With dimensions of 115x64x46 mm, the C20 box offers sufficient internal capacity to house terminals, connectors, junctions, or electrical splices. Its rectangular design facilitates space utilisation and cable organisation, enabling a clean and safe installation. The sides feature pre-punched knockouts for corrugated tubes or flexible conduits, which ease cable passage and reduce installation time. Additionally, its reinforced base prevents deformation during tightening or handling.

Professional Installation and Maintenance

Installing the C20 Box is quick and precise: simply cut the opening in the plasterboard, insert the box, and fix it using the metal clamp system. Once installed, the pressure-fit or screw-on closing cover provides effective protection against dust and particles, keeping the interior clean and safe. The design facilitates later access for inspections or cable modifications, which is especially useful in smart home installations or periodic maintenance.

Regulatory Compliance and Safety

The C20 box complies with the requirements of the Low Voltage Electrotechnical Regulations (REBT) and applicable European standards for embedded electrical components. Its insulating material and closing cover provide full protection against accidental contact and electrical leaks. Likewise, its halogen-free composition ensures minimal emission of toxic fumes in case of fire, enhancing safety in residential or commercial environments.

Applications and Professional Use

The 115x64x46 Connection Box with Cover and Metal Clamp C20 is aimed at electrical installers, maintenance technicians, and smart home professionals seeking a practical and reliable solution for installations in hollow partitions. It is ideal for homes, offices, commercial premises, and technical spaces where a compact, sturdy, and aesthetically integrated flush-mounted box is required. Its design guarantees a professional finish with a quick and secure installation.

Thanks to its robustness, metal fastening system, and functional design, the C20 represents an efficient and durable technical solution for any electrical installation project in hollow partitions.
