The TonKor Metal Roof Clamp Series provides profile-matched interfaces that secure PV module frames to the mounting structure on metal roofs. Installers locate the clamp position along the planned rail line, set the clamp on the roof profile, and complete fastening with the selected rail and clamp set; a rail-free option is also available for layouts that specify it. The series covers common metal roof types such as standing seam, trapezoid sheet, and round corrugated sheet, helping maintain consistent row geometry and a clean final appearance. Final pairing should be confirmed against the project bill of materials and the actual roof profile.
