For mounting insulation panels in concrete made from stainless steel. Tested fire resistance
  • Permitted loads under exposure to fire R30; R60; R90; R120.

  • Tested fire resistance

  • When attaching soft insulation materials that are not self-supporting, the insulation disc is simply pushed onto the insulation anchor.

  • Quick and secure mounting thanks to 2-part construction

  • Knock-in shaft has the design of a clamping sleeve and braces along the entire installation depth in the drill hole

  • Surface of anchor head suitable for use as a plaster base
