1,THUNDER PROTECTION COMPONENT: This product is a thunder protection grounding component that collect the static electricity from photovoltaic modules and photovoltaic support and leads to the ground through a grounding copper cable 2,HOW IT WORKS: This part is made up of thunder protection grounding pins and stainless steel screws. When the screw is locked, the spike on the thunder protection grounding blade will pierce the anodized layer of the aluminum guide or any other conductive metal structure surface, so that the metal structure that can contact each other forms an air tight electrostatic connection, and the electrostatic conduction on the photovoltaic module and photovoltaic support to the grounding copper wire and into the earth 3,COMPATIBLE EQUIPMENT: Solar panel grounding lugs are compatible with all kinds of aluminum photovoltaic guide rail(roof, ground, shed), C steel, U steel and H channel steel, etc. 4,QUICK INSTALLATION: PV grounding clip is easy to install, no need for many tools, allow a variety of ground conduction installation 5,5PCS IN TOTAL: The package contain a total of 5pcs solar panel earth clip, enough for you to replace and use, very convenient Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
