Features: The solar photovoltaic grounding protections gasket is applicable to photovoltaic roof, photovoltaic ground, photovoltaic barn and photovoltaic, and the protections of photovoltaic system in vegetable greenhouses. The size of the photovoltaic grounding conductive strip is 52x41mm/2.05x1.61inch, which is compatible with the guide-rail of the middle bracket. Made of 304 stainless steel, it is durable, wear-resistant and rust proof, and suitable for various installation environments. No tools are needed. During installation, it is only necessary to place it on the aluminum frame and bracket of the module, so that the lightning-protections and grounding effect of the module can be easily achieved. Puncture the anodic oxide-layer of the module frame and guide rail to realize the current conduction of the solar module frame and the installation guide rail. Specifications: Material: Stainless Steel Size: Approx. 52x41mm/2.05x1.61inch Package Includes: 50x PV Grounding Conductive Sheet note: Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order.
