A safety factor of 4:1 or 25% is generally accepted as a safe working load. Reference should be made to applicable codes for the specific working ratio. *Tested by ATEC in accordance with ASTM E488-90 and ICBO ES AC01. Minimum embedment for satisfactory anchor performance is 4 1/2 bolt diameters. Deeper embedments will yield higher tension and shear capacity.
