FAQs
What does V4A stainless steel mean?
V4A is a designation for high-grade stainless steel (similar to 316) known for its excellent corrosion resistance, making it ideal for outdoor and harsh environmental conditions.
Can this clamp be used for flat conductors?
No, this clamp is specifically designed for round conductors with diameters between 8mm and 10mm.
Is surface treatment required for this clamp?
The clamp has an untreated surface. While V4A offers inherent protection, depending on the specific environmental exposure, additional protective measures might be considered for extreme conditions, though it is designed for direct use.
What types of connections can this clamp make?
It can be used as a T-clamp, a cross clamp, or a parallel clamp, providing versatile connection options for conductors.
Does this fitting come with screws?
Yes, it is a two-piece set featuring a hexagonal screw and thread in the base part for secure fastening.
What standard does this fitting comply with?
It complies with the EN 62561-1 standard for components of lightning protection systems.
Troubleshooting
Clamp does not secure conductor firmly
Ensure the conductor diameter is within the 8-10mm range and tighten the hexagonal screw with appropriate torque. Check for any obstructions.
Visible corrosion on the clamp
While V4A stainless steel offers high resistance, inspect for potential galvanic corrosion if in contact with dissimilar metals. Ensure proper grounding practices are followed. For severe corrosion, replacement may be necessary.
Difficulty in assembly
Verify that the correct conductor size is being used and that the clamp components are properly aligned before tightening.

- Requires manual installation expertise.
Setup, Compatibility & Care
Setup:
- Ensure the conductor is clean and free of debris.
- Position the clamp around the conductor(s) as required for T, cross, or parallel connection.
- Tighten the hexagonal screw securely to ensure a firm connection.
Compatibility:
- This clamp is designed for round conductors with diameters between 8mm and 10mm.
- It is suitable for use in systems requiring compliance with EN 62561-1.
Care:
- Due to the V4A stainless steel and untreated surface, regular visual inspection for damage or excessive corrosion is recommended.
- Clean with a damp cloth if necessary; avoid abrasive cleaners that could damage the material.
