PV modules sit on rails and are held by mid clamps and end clamps. The wrong clamp slows installation and can load the frame unevenly.
Mid clamps sit between two modules; end clamps finish the outer row. Slot width must match frame height, and the rail channel must match the slider or bolt.
Zhizeng supplies anodized aluminum clamps and can match module thickness. Request a quote or browse rail accessories and clamps.
