Render fixing FIF-CN II 8

The pre-assembled drive anchor with innovative steel-plastic nail

The ETA approved fischer render fixing FIF-CN II is ideal for securely fixing pressure-resistant insulation up to 350 mm thick in the plaster façade such as polystyrene boards, mineral wool boards, wood wool lightweight panels and cork boards / coir matting in concrete, solid and perforated brick. The render fixing comprises a grey plug sleeve with attached preshaped octogonal disc and a steel-plastic nail. The FIF-CN II is set using a hammer. The innovative plastic nail with a steel point supports high loads.

Product Description


  • To set with few hammer blows.

  • The disc fits tight into the insulation thanks to its thickness of only 2.5 mm. Thus allows the application of low-cost, thin reinforcement layers.

  • High retention forces thanks to the steel tip of the compound nail.

  • Small anchoring depth of 35 mm saves on drilling times.

  • The FIF-CN II 8 is virtually free of thermal bridging due to the compound nail.

  • The compression zone in the shank allows the disc to be drawn in precisely.

  • For insulating material thicknesses up to 340 mm.
