A simple device to make fixing steelwork to walls much easier. To use, weld one of our Top Hat lugs which are pre drilled with a 25mm diameter hole to your steel frame. The large diameter hole allows you to drill straight into the wall with a masonry bit and insert the expanding fixing without having to move the heavy steelwork away. Place a top hat over the protruding stud and it will locate in the large hole. Tighten the nut onto the top hat and your steelwork is held in place.
