1 - Allowable working loads for the single installations under static loading should not exceed 25 percent (an industry standard) or the allowable load of the anchor rod.
2 - Ultimate load values in 2000 & 4000 psi stone aggregate concrete. Ultimate loads are indicated for the embedment shown in the Embedment in Concrete column. Performance values are based on the use of high strength threaded rod (ASTM A193 Gr B7). The use of lower strength rods will result in lower tension and shear loads.
