Code listed for cracked and uncracked concrete and masonry applications, the strong-bolt 2 wedge-type expansion anchor is an optimal choice for high-performance even in seismic and high-wind conditions. dual undercutting embossments on each clip segment enable secondary expansion should a crack form and intersect the anchor location; this feature significantly increases the ability of strong-bolt 2 to carry load if the hole expands.
