The Spira-Lok Tool, 10mm model is a masonry restoration anchor that is designed not to stress or fracture fragile walls in any way. This is true for both pre-existing walls and new walls that may be in the process of being constructed. It works with a wide range of different building materials, and it is also able to stand up to the heavy load required by cyclic loading. It's an excellent tool to have in your arsenal for the purposes of restoration, among others.
