Abstract: Apparatus for anchoring slabs, such as natural stone slabs, masonry wall blocks or the like, to an anchorage base, e.g. a building, comprising an angular holder having two spaced struts. Each strut includes a vertical holding leg and a horizontal supporting leg. The struts are arranged perpendicular to the surface of the anchorage base. The struts are braced together and combined with an anchor for anchoring the holder in the base, and a support member for supporting the slabs or the like. The holder and connected elements can be mass produced inexpensively by punching or stamping flat material, require no complex shaping work, exhibit a minimum weight with high load-bearing capacity, and can be easily adjustable.
