foundations, or masonry. The HPA is the heavy-duty version
of the PA anchor.
PA series – For installation into poured concrete or concrete
block walls and foundations.
PAI series – For wood I-Joist applications. An expanded 3"
on-center nail spacing reduces splitting along I-Joist ange.
Materials: HPA – 10 gauge; PA & PAI – 12 gauge
Finish: G90 galvanizing

Installation:
• Use all specied fasteners. See Product Notes, page 17.
• Allowable loads are based on either nail fastening or bolt fastening; nail and
bolt values cannot be combined.
• Install by inserting product into footing’s wet concrete. All models require a
6" embedment into concrete foundations. Courses of concrete block must
be laid over connector. Notch mudsill at connector locations. Wrap strap over
rim joist and fasten.
• Do not rely on these straps to secure concrete sections together between
cold joints; take other measures to transfer the load. If there is a cold joint
between block and foundation, the minimum embedment must be made into
the foundation.
• Based on product embedment the exposed number of fastener holes may be
reduced. Using fewer fasteners will reduce allowable loads. Reduce allowable
loads by the code prescribed allowable load per fastener, for each fastener
not installed.
• Allowable loads are based on a minimum concrete compressive strength of
2,500 psi at 28 days.
• Bolts must be ordered separately. See page 24 for available sizes.
