## Long description

The ELKO-BIS screw-on clamp for M20 grounding rods is a specialized component engineered for creating secure and reliable electrical connections within grounding and lightning protection systems. Constructed from high-quality galvanized steel, this clamp provides excellent mechanical stability and long-term resistance to environmental factors, ensuring consistent performance in various soil conditions.
Advantages
The primary benefit of this clamp is its robust design which facilitates a firm mechanical grip on M20 grounding rods, minimizing the risk of loose connections that could compromise system integrity. The galvanized finish offers a protective layer against corrosion, which is critical for components buried underground or exposed to moisture. Its straightforward screw-on mechanism allows for efficient installation, saving time during the assembly of complex earthing networks while maintaining high standards of electrical conductivity.
Suitable for
Professional lightning protection systems
Earthing installations for residential and commercial buildings
Grounding of electrical equipment and infrastructure
Connecting grounding conductors to M20 rods
When it may not be suitable
This clamp is specifically designed for M20 diameter grounding rods and will not provide a secure fit for rods of different sizes. It is also not intended for use in highly aggressive chemical environments where specialized stainless steel or copper-bonded components might be required to prevent rapid material degradation.
Key specifications
Material: Galvanized steel
Compatibility: M20 grounding rods
Application: Grounding and lightning protection systems
Connection type: Screw-on
How to use
To install the clamp, ensure the M20 grounding rod is clean and free of debris. Position the clamp over the rod and tighten the screw mechanism firmly to achieve a secure mechanical and electrical bond. Ensure that the grounding conductor is properly inserted and secured according to local electrical safety regulations and project specifications.
What to consider before purchase
Verify the diameter of your grounding rod matches the M20 specification
Check local building codes for material requirements in your specific soil type
Ensure compatibility with the grounding conductor material to prevent galvanic corrosion
Usage recommendations
Regularly inspect the connection point during routine maintenance of the grounding system to ensure the clamp remains tight and free from significant corrosion, especially in areas with high soil acidity or moisture levels.
