The Strong-Bolt 2 wedge expansion anchor is a great choice for high performance needs, including seismic and high-wind conditions. These anchors are code listed for concrete, cracked concrete and other masonry applications. Each clip has dual undercutting embossments, which enable a secondary expansion in the case of a crack forming that intersects the anchor location. If the hole expands, this significantly increases the ability of the Strong-Bolt 2 to continue to carry the load.
