Allowable loads are calculated using safety factor of 5. <br /> 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 <br /> within one inch of a vertical joint. See figure 7 for anchor installation locations in end-of-wall and vertical members of wall openings. <br /> 3 Anchors may not be installed within 1-1/4"in any direction of a head joint. <br /> 4 For load values at edge distances between listed values linear interpolation is permitted. <br /> 5 Critical spacing equals minimum spacing. <br /> 6 Minimum end distance applicable to top-of-wall and end-of-wall and does not apply for wall openings such as windows. <br /> KWIK HUS-EZ SCREW ANCHOR-July 2020 19 <br />
