- The tabulated allowable loads are based on a safety factor of 5.0 for installations under the IBC and IRC. For installations under the UBC use a safety factor of 4.0 (multiply the tabulated allowable loads by 1.25).
- Listed loads may be applied to installations on the face of the CMU wall at least 1 1/4 inch away from headjoints.
- Values are for 8-inch-wide CMU Grade N, Type ll, lightweight, medium-weight and normal-weight concrete masonry units conforming to UBC Standard 21-4 or ASTM C90. The masonry units must be fully grouted with grout complying with UBC Section 2103.4 or IBC Section 2103.12. Mortar must be Type M or S prepared in accordance with Section 2103.3 of the UBC and UBC Standard 21-15, or IBC Section 2103.8. The specified compressive strength of masonry, f'm, at 28 days must be a minimum of 1,500 psi.
- Embedment depth is measured from the outside face of the concrete masonry unit.
- Drill bit diameter used in base material corresponds to nominal anchor diameter.
- Allowable loads may be increased by 33 1/3 percent for short-term loading due to wind and seismic forces.
- Tension and Shear loads for the Wedge-All anchor may be combined using the parabolic interaction equation (n=5/3).
- Refer to allowable load adjustment factors for edge distance.
