1 All values are for anchors installed in fully grouted concrete masonry with minimum masonry prism strength of 1,500 psi . Concrete masonry units may be lightweight , medium-weight or normal-weight conforming to ASTM C90 . Allowable loads are calculated using safety factor of 5 .
2 See figure 6 and 7 for allowable anchor installation locations on the top of grout-filled concrete masonry walls . Anchors may not be installed within one inch of a vertical joint . See figure 7 for anchor installation locations in end-of-wall and vertical members of wall openings .
3 Anchors may not be installed within 1-1 / 4 " in any direction of a head joint . 4 For load values at edge distances between listed values linear interpolation is permitted . 5 Critical spacing equals minimum spacing . 6 Minimum end distance applicable to top-of-wall and end-of-wall and does not apply for wall openings such as windows .
