1 The admissable anchor location must be established to prevent damage to the prestressed cable during the drilling process. Verify the location and height of the cable with the hollow core
plank supplier to confirm admissable anchor location.
2 Minimum compressive strength of prestressed concrete is 7,000 psi. Published results represent the average results conducted in local base materials. Due to variations in materials and
dimensional configurations, on-site testing is required to determine the actual performance
3 Allowable loads calculated with a factor of safety of 4.

is the maximum installation torque that may be applied with a torque wrench.
2 Because of variability in measurement procedures, the published torque of an impact tool
may not correlate properly with the above setting torques.
Over torquing can damage the anchor and/or reduce its holding capacity.
