The Strong-Bolt 2 wedge anchor is the next-generation solution for cracked and uncracked concrete. Following rigorous testing according to ICC-ES acceptance criteria, the Strong-Bolt 2 anchor received classification as a Category 1 anchor, the highest attainable anchor category for performance in cracked concrete under static and seismic loading. Available in stainless steel, it is code-listed by ICC-ES under the 2009 IBC requirements for post-installed anchors in cracked and uncracked concrete. The popular 3/8" diameter, the Strong-Bolt 2 anchor is ideal for MEP applications in cracked concrete, such as hanging pipes, struts, equipment anchorage and other fixtures overhead. The anchor is also effective for lightweight- concrete applications, including concrete-over-metal decking. Category 1 anchor classification: The Strong-Bolt 2 anchor received classification as a Category 1 anchor, which is established by performance in reliability tests in accordance with AC193 and ACI355.2 test criteria. Category 1 is the highest attainable anchor category for reliability. Tri-segmented clip: Each segment adjusts independently, increasing follow-up expansion should the hole increase in size as a result of a crack. Dual embossments on each clip segment: Enables clip to undercut into the concrete thereby increasing follow-up expansion should a crack occur. The 3/8" anchor solution approved for 3-1/4" concrete thickness: The Strong-Bolt 2 anchor can be installed in cracked concrete with a minimum thickness of 3-1/4", including concrete-over-metal decking. High-strength alloy clip on carbon-steel anchors: This special alloy clip offers improved performance.
