The Fischer long-shank dowel SXRL-FUS is approved for use with the Fischer hexagon screw featuring a molded washer and integrated TX50 bit holder for multiple fixings of non-load-bearing systems in masonry, concrete, and aerated concrete. In hollow block masonry, the two expansion zones of the dowel distribute force evenly, while in aerated concrete and solid building materials, these combine to form a long expansion element. With the safety screw made of galvanically galvanized steel, the long-shank dowel is suitable for securing metal substructures for facades, ceilings, and roofs.
