fischer DuoPower Wall Plugs

The fischer DuoPower plug is an intelligent 2-component plug that can be used in both solid and cavity walls. The intelligent design of this universal plug makes it suitable for fixing in all building materials, making it an ideal one-plug-fixes-all solution to carry on site.

The fischer DuoPower adjusts itself automatically to the building material and transfers the highest loads through the three product functions of folding, expanding and knotting. The DuoPower range gives the user very good feedback from the plug when fastening, helping to prevent over-tightening which can damaged both the wall and fixtures.

Substrate Types

The fischer DuoPower plug can be installed all building materials and will work in cavity, aerated and solid substrates. The images below show how the plugs deform to suit the material they are being fixed into. You do not need to do anything to initiate either function - the plug will expand automatically to suit whichever substrate it is being fixed into.

Loading Data Table

The below load data table is a useful reference table with recommended loads for all of the different DuoPower plug sizes in different common building materials. The loadings are all given in Kilonewtons - for a rough conversion to Kilo you can multiply by 100, so for example 0.30 kN x 100 = 30 Kilo.
