Thanks to the clever combination of design and material, the fischer frame fixing DuoXpand bites optimally into all building materials. While the grey main body, made of high-quality nylon provides a strong hold, the red material component offers additional security in the drill hole. The DuoXpand is approved according to ETA as a multiple fixing for non-load-bearing systems in concrete, masonry and aerated concrete. The range includes diameters 8 and 10 mm each with fischer safety screws made of zinc plated and stainless steel, countersunk head and hexagonal head with moulded-on washer.
