PM F is the pre-assembled clamp for PV panels with aluminium frame. Available in the PM F end clamp or PM C central clamp variants. The PM clamp is available in different variants depending on the thickness of the PV panel. PM F features a hammer nut with a special plastic cage to facilitate positioning of the nut inside the central groove of the rail. The spring keeps the clamp raised until it is tightened to facilitate positioning of the PV panel.
