This FIXtainer DUOPOWER/DUOTEC dowel set from Fischer can be used for various masonry tasks in the home, garage, and workshop. The clever 2-component dowel set is suitable for fastening all types of building materials, even for aerated concrete and bridge plaster. It automatically adapts to the building material and transmits high loads through its three functions: folding, expanding, and knotting. The narrow dowel edge prevents the dowel from slipping in the drill hole. This Fischer set is perfect for the most common applications and building materials, providing excellent feedback from the dowel. Thanks to the included plastic box with a transparent lid and removable compartments, you can easily store the components and select the appropriate one. The box is also equipped with a carrying handle for easy transport.
