The concealed stand-off installation solution using A4 stainless steel undercut anchors for heavy natural stone façade panels. This technology defines a constant distance between the front of the panel to the connection level on the FZP II anchor (RWT = remaining wall thickness as a reference dimension for drilling. This technology can be used to compensate the tolerances of panel thicknesses to create a flat façade surface by using stand-off installation anchors.
The adapted shape of the undercut anchor ensures a positive-locking attachment free from expansion pressure in a conical undercut drill hole.
The fixing of the undercut anchor is not visible on the exposed side, creating a visually attractive and consistent façade surface.
Setting the anchor using undercut technology allows the user to always select the optimal structural position in the façade panel. This greatly reduces panel deflection.
The anchor allows for higher pull-out loads, compared to commonly available systems.
Using a constant remaining wall thickness as a reference value when drilling holes allows users to compensate panel thickness tolerances.
