Verify the location and height of the <br /> cable with the hollow core plank supplier to confirm admissible anchor location. <br /> 2 Minimum compressive strength of prestressed concrete is 7,000 psi.Published ultimate loads represent the average results conducted in local base materials. <br /> Due to variations in materials and dimension]configurations,on-site testing is required to determine the actual performance. <br /> 3 Allowable loads calculated with a factor of safety of 4. <br /> Figure 8- Installation of Hilti KH-EZ, KH-EZ P, KH-EZ PM, <br /> KH-EZ PL, KH-EZ C and KH-EZ CRC in hollow core concrete <br /> QAnchor <br /> f <br /> hef 1 1 t <br /> KWIK HUS-EZ SCREW ANCHOR-July 2020 21 <br />
