70mm Capex bars are pre-drilled and come with their own fixing screws and end caps, as well as Rag 55 gasket - a flat strip of gasket 55mm wide and in length matching that of the Capex bar. The gasket is laid flat along the rafter, the sheets sit on top with a small gap, and the Capex bar is laid on top (see product images).
Installation tip: The Capex bar is pre-drilled and supplied with fixing screws. Hand tightness only - do not overtighten the screws!.
