R-GOK-N Nylon telescopic sleeve with round plate

Telescopic nylon sleeve for flat roof insulation fixing. 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. 

  • Round plate eliminates the need of positioning the fixing during the installation, the bottom part of the connection sleeve is designed to carry very heavy loads during operation of the roof.
  • 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.
  • Should be used with combination of any Rawlplug roofing screws: WBT to concrete, WX/WO to steel sheat, WW to wood.
