Lightning protection systems. Lightning can easily damage a number of different building materials, and the large electrical currents can cause fires within the interior or even side flashes. Side flashes are small explosions of highly pressurized, super-heated air that occur inside the nooks and crannies of structure materials.
You will need at least the following items for your lightning protection system: Conductor cable. Lightningrods. Clips to secure the cable in place. Ground rods or ground plates. Ground rod clamps. Screws or nails for the cable clip holders. Possibly some crimp or bolt tension parallel splicers.
