The TonKor PV Module End Clamp is installed at the boundary of a PV row to secure the module frame to the mounting rail on rooftop or ground-mount structures. By closing the edge, it helps preserve straight strings, protects the finishing line, and keeps inspections simple. The workflow is direct: set the rail, position the clamp at the frame contact surface, and tighten with the selected hardware to complete the edge. Pairing should be confirmed against your project bill of materials and the chosen rail and clamp family.
