Simpson StrongTie's Heavy Purlin Anchor also features a strap that can be bent one full cycle (vertical then horizontal) to accommodate framing layout needs. The hardware must hook around rebar in the concrete wall and uses all specified fastener holes for maximum load capacity. Allowable load values apply to horizontal installation into concrete or masonry walls with proper edge spacing. It offers the highest capacity among Simpsons concreteanchored purlin connections for heavy framing design.
