Fischer FID II insulation anchor is suitable for lightweight attachments, such as outdoor lights, house numbers, or doorbells, mounted on external thermal insulation composite systems. Compatible with standard screws with a diameter of 3.5 - 4.5 mm. Maximum stability due to glass-fiber-reinforced plastic. The anchor edge is not visible even with narrow attachments due to the minimal head diameter. Thanks to the special tip geometry, the anchor can be screwed through plaster layers up to 10 mm thick without pre-drilling, saving time. The FID II is easily screwed in using a standard TX40 screwdriver bit. Fischer insulation anchor is compatible with all common insulation materials.
