Strong Frame® Anchorage Extension Kit 

Strong Frame® Anchorage Extension Kit

The Strong Frame anchorage extension kit extends the anchor rods in the MFSL and MFAB anchorage assemblies to allow for anchorage in tall stemwall applications where embedment into the footings is required. Made from ASTM F1554 Grade 36 rod or ASTM A449 rod, the extension kits feature heavy hex nuts that are fixed at the correct position to go underneath the shear lug or template and a “No Equal” (≠) head stamp for identification. Coupler nuts are included with each kit. Kits available with hot-dip galvanization for corrosion protection when required, lead times apply.
