  • Can be combined with any Rawlplug roofing screws: WBT screws for concrete, WX or WO screws for trapezoidal metal sheet and WW screws for timber.
  • Impact-resistant material used ensures constant mechanical properties over the lifetime of a roof. Also, retains its properties over a wide temperature range. 

  • Internal sleeve design allows pre-assembly with any Rawlplug roofing screw, shortening installation.

  • The cone’s optimal shape facilitates speed and ease of installation through the thermal insulation.
  • Guarantees the highest load capacity of the roof construction for both static and dynamic loads in accordance with ETAG006.
