Features

Telescopic sleeve for flat roof insulation fixings

  • High impact - resistant material used ensures constant mechanical properties over the lifetime of a roof. Also, retains its properties over a wide temperature range.
  • Should be used with combination of any Rawlplug roofing screws: R-WBT to concrete, R-WX/WO to steel sheat, R-WW to wood.
  • 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 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.
  • The reduced diameter makes it easier to pierce the membrane and install in dense materials such as PIR / PUR and mineral wool.
  • Pre-assembled sleeve with a screw shortens the assembly time, additionally it has a security in the form of a locking O-ring, which prevents the screw from slipping out.
  • The engraving on the plate reduces the effect of the notch and crack propagation (spreading of damage in the material subjected to stress).
