Air-Termination Rods / Tips
Additional fasteners, e.g. DEHNiso spacers, are necessary depending on the gust wind speed.
Note: Permissible roof loads have to be considered and checked with the constructor where required.
Rod Holders DEHNhold

Telescopic air-termination rods
The respective wind loads and the quantity of concrete bases can be found in the installation instructions.
The maximum free length refers to the distance between the rod tip and the upper holder (fixing point).
For reasons of stability, the centre holder (3 fixing points) should be mounted directly below the upper holder if possible. The distance must not be more than 15 cm. The lower holder (fixing point) has to be installed within a range of ≤ 15 cm at the end of the air-termination rod.
Telescopic, self-supporting air-termination rods up to 8 m
The stackable concrete base (weight 17 kg / part no. 102 010) and the plastic base plate (part no. 102 050) have to be ordered separately.
Note: Permissible roof loads have to be considered and checked with the constructor where required.
Air-Termination Rods D40
The maximum free length refers to the distance between the rod tip and the upper holder (fixing point).
For reasons of stability, the centre holder (3 fixing points) should be mounted directly below the upper holder if possible. The distance must not be more than 15 cm. The lower holder (fixing point) has to be installed within a range of ≤ 15 cm at the end of the air-termination rod.
Stands for air-termination rods D40 and GRP/Al supporting tubes
The stackable concrete bases, the plastic base plates, the base holder set for holding additional concrete bases and the adapter set for D40 air-termination rods are each available separately in the accessories.
Supporting tube stand for GRP/Al supporting tubes and Ø40 air-termination rods
The D40 air-termination rods / supporting tubes must be ordered separately.
Concrete bases
Note: Please contact us to find out whether the material of the roof conductor holder or base plate is compatible with the roof elements.

Supports for Air-Termination Rods D40 and DEHNcon-H
Mast holder, heavy version
The heavy version of the mast holder enables the mounting of air-termination masts with a diameter of Ø40-50 mm (upright) and Ø55-100 mm (transverse).
Telescopic Lightning Protection Mast with Screw Foundation
The masts are erected in a screw foundation.
No digging or foundation work necessary.
The screw foundation is screwed into the natural ground and fixed in place by three earth rods Ø20 mm, length 1500 mm (Part No. 620 151). These must be ordered separately.
The air-termination masts are designed according to Eurocode.
These calculations are based on a natural ground pressure of 0.02 kN/cm2 (e.g. loamy, sandy, gravelly soil of medium density).
Telescopic Lightning Protection Mast for Bucket or Concrete Foundations
The masts are erected in a bucket foundation (pre-fabricated) or an on-site concrete foundation with foundation basket (to be ordered separately).
For detailed information on the plug-in system, foundation and erection, please see the installation instructions.
Advantages of the air-termination mast system:
- Excavation work can be completed in advance
- Erection in (prefabricated) bucket foundation on site with comparatively little effort, or
- Erection in on-site concrete foundations with foundation basket (concrete curing time to be observed for scheduling and erection)
- Version with flange plate for fast mounting
- Easily adjustable with M24 threaded bolts
- Detailed mounting instructions
- Verifiable statics (upon request)
- Air-termination rod, HDG steel, Ø42 / 25 / 15 mm, length 2400 or 5400 mm, with M20 thread and lock nut
- Conic mast segments
- Flange plate with terminal lug for earth connection borehole Ø12 mm (for Ø10‑mm round conductor, e.g. with KS connector, part no. 301 019)
Max. transport length 6 m.
Bucket Foundations for Telescopic Lightning Protection Masts
No concreting on site.
For detailed information on the telescopic system, foundation and erection, please see he installation instructions.
Foundation Basket for On-site Concrete Foundations
For detailed information on the telescopic system, foundation and erection, see the installation instructions.
Air-Termination Rods for Metal Roofs
It is fixed at the end of the braces (Ø11-mm holes) by four holders for metal roofs.
The holders must be selected according to the roof profile (round standing seam part no. 123 040, clamping seam part no. 123 041, standing seam 123 042, without seam for riveting or screwing 123 043).
Air-Termination Rod for Trapezoidal Roofs
The air-termination rod is placed in the gap between the trapezoidal seams profile. The variable base frame can be adjusted to all trapeziodal profiles. The special holder for the air-termination rod can compensate roof inclinations up to 10°.
Air-Termination Rod for Ridge and Hip Tiles
The clamping bracket must be adjusted to the diameter of the ridge tiles before it is used to secure the air-termination rod.
Holders for Air-Termination Systems on Ridge and Hip Tiles
The holder is mounted using a tensioning strap. One clip is permanently fixed to one end of the tensioning strap. The holder can be adjusted to various types of ridge tiles using the adjustable clip at the other end.
Air-termination tips / rods or spacer bars have to be ordered separately.
Rod Holder for Gable Roofs
At the chimney, the air-termination rod requires additional fixing e.g. by means of DEHNiso spacer.
Pipe Clamp for Air-Termination Rods
The maximum free length of the respective air-termination rod according to the wind load must be considered for installation.
Angled Air-Termination Tips
A distance of 15-20 cm between the seam clamps and the free length of 80-85 cm should be ensured.
The air-termination tip is adjustable to the inclination angle of the PV system. The standard type is 55° angled which corresponds to a PV system inclination of 35°.
Air-Termination Tips
Air-Termination Stud
The air-termination stud and the conductors may either be installed in concrete or in the joints between the decks.
