The fischer expansion plug SB is the original and best; over the decades, it has proven itself a million times over. The plastic fixing is solely made of high-quality nylon. This means that the plug is particularly robust during installation and ensures permanent safety. As the plug only expands in two directions, it is possible to direct the expansion forces so that they run parallel to the edge of the building material by turning the plug. When fixing close to the edge, this prevents the building material from spalling. The fischer expansion plug SB is also delivered with a round hook and is recommended for fixing into solid building materials.
