The Fischer porous concrete anchor FPX-I is made from galvanized steel. After pre-drilling, the FPX-I is simply hammered in. No hole cleaning is necessary. The Fischer porous concrete anchor is tightened with a hex key using a cordless screwdriver or a ratchet. This pulls the cone into the expansion sleeve. The four wings create an undercut in the hole. After expansion, the hex key is automatically disengaged. The Fischer porous concrete anchor FPX-I is ideally suited for securing suspended ceilings, railings, or kitchen cabinets in porous concrete.
