With DuoPower, DuoTec, and self-tapping DuoBlade screws with plugs, this comprehensive FIXtainer plug and screw set DUOLINE from Fischer meets all requirements in the home, garage, and workshop. The smart DuoPower 2-component plugs with screws are suitable for fastening all types of building materials, even aerated concrete. They automatically adapt to the building material and transfer high loads through three functions (folding, spreading, and knotting). The narrow plug rim prevents the plug from slipping in the drill hole. The DuoTec plug with a flexible screw receptacle can be used as a expansion plug in concrete or wood. The black metal tip of the DuoBlade plugs ensures easy and secure installation. This hardware set from Fischer is perfect for the most common applications and building materials, providing excellent hold. Thanks to the included plastic box with a transparent lid and compartments, you can easily store the hardware and select the appropriate ones. The box also features a carrying handle for easy transport.
