Product Information
Full details
This DEHN rebate clamp is designed for professionals installing additional air-termination systems on metal roofs, particularly those with clamping seams. Its key benefit is secure conductor attachment with high lightning current carrying capability, up to 100 kA (10/350 µs) when used in pairs. A caveat to consider is that its full tested lightning current capability depends on the specific roof profile and the use of a pair of tested holders.

FAQs
What material is the DEHN rebate clamp made from?
The clamp is constructed from V2A stainless steel, offering excellent corrosion resistance.
What is the maximum lightning current this clamp can handle?
When used in a pair with holders tested for the specific roof profile, it can handle up to 100 kA (10/350 µs).
What size round conductors can this clamp accommodate?
It is suitable for round conductors with diameters ranging from 6mm to 10mm.
On what type of roofs is this clamp designed to be used?
It is specifically designed for metal roofs that have clamping seams.
How is the clamp fastened to the roof?
It is fastened using flat round screws.
What is the clamping range of this holder?
The clamping range for the conductor is between 0.7mm and 8mm.
Does this product require any additional components for full performance?
Yes, for its maximum tested lightning current carrying capability, it requires a pair of roof conductor holders (clamps or clamping pieces) tested for the respective roof profile.
Troubleshooting
Conductor is not securely held
Check that the conductor diameter is within the 6-10mm range and that the clamp's fastening mechanism is fully tightened to engage the 0.7-8mm clamping range.
Difficulty attaching clamp to roof seam
Ensure the roof clamping seam is clean and that the clamp is correctly aligned with the seam profile. Verify the correct flat round screw is used for fastening.
Concerns about lightning current rating
Confirm that two rebate clamps are used, and that both have been tested and certified for the specific roof profile being used.

Setup, Compatibility & Care
Setup:
- Ensure the metal roof clamping seam is clean and free of debris.
- Position the DEHN rebate clamp onto the clamping seam.
- Insert the flat round screw through the clamp and into the seam, tightening securely.
- Place the round conductor (6-10mm diameter) into the clamp.
- Tighten the clamp's fastening mechanism to secure the conductor within the 0.7-8mm clamping range.
- For maximum lightning current capability, install a second holder and ensure both are tested for the specific roof profile.
Compatibility:
- Suitable for round conductors with diameters from 6mm to 10mm.
- Designed for metal roofs featuring clamping seams.
- Use with pairs of tested holders for full lightning current certification (100 kA).
Care:
- Periodically inspect the clamp for any signs of corrosion or damage.
- Ensure the conductor remains securely clamped.
- Clean with a damp cloth if necessary; avoid abrasive cleaners.
