Some building codes require a mechanical connection between the stone veneer panel and the building structure.   The TS106 Mechanical Anchor makes a bridge connection between the TS121 Perimeter Frame and a self-locking wedge type of expansion anchor which is shop-inserted into a prepared hole in the back of the fascia panel.   When properly installed, this self-locking anchor insert produces a substantial pull-out value which varies with the physical characteristics of the particular type of stone involved.
