THUNDER PROTECTION COMPONENT: This product is a thunder protection grounding component that collects the static electricity from photovoltaic modules and photovoltaic support and leads to the ground through a grounding copper cable 2. Working principle: 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: Compatible with all kinds of aluminum photovoltaic guide rail(roof, ground, shed), C steel, U steel and H channel steel, etc. 4. QUICK INSTALLATION: Easy to install, no need for many tools, allows a variety of ground conduction installation 5. 10PCS IN TOTAL: The package contain a total of 10pcs grounding clip, enough for you to replace and use, very convenient Specification: Item Type: Solar Mounting System Grounding Clip Material: Aluminum and stainless steel.
