The duo of 2-component material and 3 product functions ensures high material displacement, thereby facilitating higher loads. Depending on the building material, the plug activates the optimum product function (expansion, folding, knotting) for the best hold. The DUOPOWER is suitable for pre-positioned and pushthrough installation. Suitable for wood, chipboard and stud screws. Screw length = plug length + fixture thickness + 1x screw diameter. In the case of board building materials, the threadless part of the screw must not be longer than the fixture.
