Simple lightning rod " Franklin " Blunt Tip Type
Franklin lightning rod, which are blunt tip tapered, have a perfectly slender and attractive point. They exist in nickel/chromium-plate copper and stainless steel versions. They have a standard length of 2,4m and can be extended by the addition of treated steel and stainless steel elevation rods. These systems do not require guying and can be up to 7 or 8 m long. The tip of 2F Franklin lightning rods features a solid point of marine bronze or stainless steel.

" Field trial tests in the United States, carried out over many years research have confirmed that blunt lightning rods are struck by lightning in preference to sharp pointed lightning rods."

" Industrial stack " model
This model is only available in stainless steel, This points are bent to keep them out of fumes and corrosive vapours. They are generally used in quantities of two or more, depending on the diameter of the stack (see UTE Standard C 17100)
