## Summary description

The ELKO-BIS 117.2 CZ clamp is designed for reliable connection of foundation earth electrodes to reinforcement bars with a diameter of 28 mm. This high-quality component ensures electrical continuity in grounding systems, providing a secure and durable mechanical connection. Ideal for professional electrical installations in construction, it facilitates effective lightning protection and grounding of building structures.

## Long description

The ELKO-BIS 117.2 CZ foundation earth electrode and reinforcement clamp is a professional-grade component engineered for establishing secure electrical connections between foundation grounding systems and reinforcement bars. Specifically designed for bars with a 28 mm diameter, this clamp ensures high mechanical stability and consistent electrical conductivity, which are essential for the integrity of building grounding and lightning protection systems.
Advantages
This clamp offers exceptional durability and resistance to environmental factors, making it suitable for long-term installation within concrete foundations. Its robust construction ensures that the connection remains tight and reliable over time, preventing loosening due to thermal expansion or structural shifts. By providing a low-resistance path for electrical currents, it significantly enhances the safety and effectiveness of the entire grounding network in modern construction projects.
Suitable for
Connecting foundation earth electrodes to 28 mm reinforcement bars
Professional lightning protection system installations
Grounding of building structures and foundations
Ensuring electrical continuity in reinforced concrete elements
When it may not be suitable
This clamp is specifically dimensioned for 28 mm diameter reinforcement bars and will not provide a secure fit for bars of different sizes. It is not intended for use in applications requiring connection to non-metallic materials or for grounding systems that do not utilize standard reinforcement steel.
Key specifications
Compatible reinforcement bar diameter: 28 mm
Material: Corrosion-resistant metal alloy
Application: Foundation grounding and lightning protection
Mechanical connection type: Bolt-tightened clamp
How to use
To install the clamp, position it around the 28 mm reinforcement bar at the designated grounding point. Insert the foundation earth electrode into the clamp assembly and tighten the bolts firmly to ensure a solid mechanical and electrical bond. Ensure that the contact surfaces are clean and free of debris or heavy rust before tightening to achieve optimal conductivity.
What to consider before purchase
Verify the exact diameter of your reinforcement bars to ensure compatibility
Ensure the clamp meets the specific grounding requirements of your building project
Check local electrical safety standards for foundation grounding installations
Usage recommendations: Always perform a continuity test after installation to verify that the grounding system meets the required electrical resistance standards. Ensure that the clamp is fully embedded in concrete according to structural engineering specifications to protect it from long-term corrosion.
