Fischer duotec allows very heavy load support for overturning dowels. The dowel for plasterboard reduces the number of fixings and maximizes safety. As a member of the DUO line, the DUOTEC consists of two plastic components. The red and hard component of the plug sleeve allows uniform load distribution, and the gray and soft prevents causing damage to the plate surface during fixation, thereby increasing the load. In plate applications, behind which there is a gap, the DUOTEC is used as a tipping dowel. In solid materials, the plug can also be used as an expansion plug. Weight: 0.12345886672 pounds.
