The Fischer universal plug is the all-rounder made from high-quality nylon. The plug holds in concrete, as well as in aerated concrete, masonry, and drywall and gypsum fiberboards. In these building materials, the plug knots securely. The molded edge is practical as it prevents the plug from slipping when inserted into the drill hole. With the Fischer universal plug UX, you can attach items such as lights, curtain tracks, lightweight cabinets, and baseboards.
