<br />1 All values are for anchors installed in fully grouted masonry with minimum masonry prism strength of 1,500 psi. Concrete masonry units may be lightweight, medium -weight or normal -
<br />weight.
<br />2 Anchors may not be installed within one inch in any direction of a vertical joint.
<br />3 Linear interpolation of load values between minimum spacing sm,, and critical spacing s,, and between minimum edge distance c_ and critical edge distance
<br />c�, is permitted. spa spa

<br />5 See Figure 5 on Page 21 of this document for anchor locations for anchor locations.
<br />6 Embedment depth is measured from the outside face of the concrete masonry embedment.
<br />7 Critical spacing sir is the anchor spacing where full load values may be used. The minimum spacing smm is the minimum spacing for which values are available and installation is
<br />recommended. Spacing is measured from the center of one anchor to the center of the adjacent anchor.
<br />8 Load reduction factors are multiplicative, both spacing and edge distance load reduction factors must be considered. Load values for anchors installed at less than car or s., must be
<br />multiplied by the appropriate load reduction factor based on actual edge distance (c) or spacing (s).
<br />9 The critical edge distance car is the edge distance where full load values may be used. The minimum edge distance cm., is the minimum edge distance for which values are available and
<br />installation is recommended. For tension, c�, equals cm, Edge distance is measured from the center of the anchor to the closest edge.
<br />10 Load values must be reduced by 21 % for installations within 1-1/4 inches of the bed joint.
<br />11 Load values must be reduced by 13% for installations within 1-1/4 inches of the bed joint.
