– Manufactured from high conductivity hard drawn copper or aluminium, with rolled threads. Supplied complete with locknut
Note: during high winds and extreme weather conditions air rods over 1000 mm long can be subjected to fatigue mechanisms.
It is therefore recommended that additional supports are considered before installation
Standards
“Field Trials in the United States, carried out over many years of research have confirmed that
blunt air rods are struck by lightning in preference to taper pointed air rods.”
