Purlin Anchors – PA & PAI series<br />
PA series – For installation into poured concrete or concrete block walls and foundations.<br />
PAI series – For wood I-Joist applications. An expanded 3˝ on-centre nail spacing reduces splitting along<br />
I-Joist flange.<br />
Holdowns<br />
50<br />
Materials: 12 gauge<br />
Finish: G90 galvanizing<br />
Options: PA18, PA23 and PA28 are available in Triple Zinc.<br />
To order, add TZ to end of stock number, as in PA18-TZ.<br />
Codes: Load values are derived from data submitted to various<br />
North American building code evaluators.<br />
<strong>Installation</strong>:<br />
Typical PA purlin<br />
• Use all specified fasteners. See Product <strong>Notes</strong>, page 10.<br />
• Minimum concrete strength is 2,000 psi.<br />
installation<br />
• The factored resistance for bolts are based on parallel to grain loading with a 3˝ minimum<br />
member thickness. Reduce load per code requirements when minimum member thickness is<br />
not achieved.<br />
• Minimum concrete edge distance is 4˝ for PA & PAI series.<br />
• Minimum concrete block edge distance is 20˝.<br />
• Designer may specify alternate fastening schedules. Refer to Nail Specification Table on<br />
page 14 for nail shear values. Load values shall not exceed published factored resistance.<br />
• No anchor bolts are needed for achieving efficient stress transfer from framing to concrete<br />
walls or foundations.<br />

1) Factored resistances have been increased 15% for short-term loads such as wind and earthquake; reduce for other load durations in accordance with the code.<br />
<br />
3) Values are based on the use of either nails or bolts; nail and bolt values cannot be combined.<br />
4) 16d sinkers or 10d common nails may be substituted for the specified 16d common nails at 0.85 of the table loads.<br />
5) Minimum nail embedment shall be 8 nail diameters (typ).<br />
6) For alternate nail schedule and load values consult <strong>USP</strong>.<br />
7) Minimum quantity of fasteners to be installed. Product may have additional fastener holes not needed to meet published allowable load of product.<br />
