fischer Insulation support DHK 45/100

The cost-effective plastic insulation support for all pressure resistant insulating boards.

Art.-No. 80895
Top Features
  • Reduced drilling. Optimised geometry lowers anchorage depth.
  • Simple Hammerset installation saves time and costs.

Product Description

The fischer insulation support DHK is the cost-effective plastic insulation support for insulating boards with high compressive strength. The DHK is knocked in the push-through installation using a hammer. When knocking in, the ribs expand in the drill hole and the DHK is ideally pressed in. The fischer insulation support DHK is suitable for anchoring insulating boards in solid and perforated brick, concrete, and aerated concrete.
  • The optimised geometry of the expansion section ensures a low anchorage depth and reduces the amount of drilling required.
  • Flexible pins in the plate area adapt to the insulating material, and ensure a sustained contact pressure.
  • The simple hammerset installation allows for a quick installation process and thus reduces workload.
  • The DHK 45 is suitable for use in pressure-resistant insulating boards and reveals.
