fischer Insulation Fixing FID II 50 mm Wall Anchors Fast Installation No Pre-Drilling Required Spiral Thread for EPS and Insulation Boards for Letter Boxes, Lamps and Motion Detectors - 50 Pcs
Since the anchor is set exclusively in the insulation itself, fixtures can be installed without thermal bridges.
The FID 50 is used in thin insulating boards from 1.96 inches (50mm). The FID 90 is used in thicker insulating boards, and can bear higher loads.
The geometry of the FID allows for a simple installation in thin layers of plaster, without the need for pre-drilling, thus saving a stage of installation.
The bit mounting allows for setting with standard tools, thus allowing for a fast and economic installation.
