Fischer Duebel insulation plugs

(This text is machine translated) The FID 90 insulating material anchor from Fischer is ideal for fastening light attachments in plastered and unplastered insulation boards made of polystyrene and polyurethane. It can be set into the insulation board with a cordless screwdriver or by hand. The special thread spiral cuts itself into the insulating board with a form fit. Attachments are attached to the FID 50 with a 4.5 mm screw. To prevent water from entering the insulating material, the dowel edge should be sealed after pre-positioned installation. The FID 50 can be used in thin insulation boards from 50 mm. The use of the FID 90 is recommended in thicker insulating boards.
