	<li>The stand-off is the distance from the interior flange of the stud to the face of the supporting structure (see illustration below).<br>

	  beyond the exterior flange of the stud; &ldquo;&mdash;&rdquo; designates conditions where fastener pattern will not fit on stud.</li>
	<li>A tabulated maximum stand-off of 12 1/4&quot; is based on three anchors. For two anchors, maximum stand-off is 13 1/4&quot;.</li>
	<li>A tabulated maximum stand-off of 11&quot; is based on three anchors. For two anchors, maximum stand-off is 12&quot;.</li>
	<li>For FCB fixed connectors (pp. 47&ndash;49), minimum indicates fill all round holes, and maximum indicates fill all round and triangle holes.</li>
