R-GOK Telescopic sleeve with round plate

Telescopic sleeve for flat roof insulation fixings. Combined together with the corresponding screw allows application in all types of substrates.

Features and benefits

  • Impact-resistant material used ensures constant mechanical properties over the lifetime of a roof. Also, retains its properties over a wide temperature range. 

  • The lenticular shape of the plate ensures a firm pressure on the membrane and no possibility of dragging and deforming the plate during assembly
  • Internal sleeve design allows pre-assembly with any Rawlplug roofing screw, shortening installation.

  • The reduced diameter makes it easier to pierce the membrane and install in dense materials such as PIR / PUR and mineral wool
  • The lower part of the connector telescope has been designed in the shape of a cone with an optimum angle of inclination which significantly affects the speed of its installation.
  • Guarantees the highest load capacity of the roof construction for both static and dynamic loads in accordance with ETAG006.
