The quadruple expansion of the SX peg allows for optimal transmission of forces in the building material. In addition to its expansion, the high-quality nylon used for its production ensures a secure and permanent fixation. The SX fischer dowel is the first choice for fixing, for example, of lighting, sheaths, bathroom accessories and lightweight wall cabinets in concrete and aerated concrete, but also in masonry made of solid or hollow building materials. The flange versions prevent the dowel from slipping into the borehole. Versions with larger anchoring depths are ideal for fasteners in hollow building materials, aerated concrete and for plaster cladding
