1 The tabulated allowable load values are for the powder-actuated ceiling clip assemblies only , using a safety factor that is greater or equal to 5.0 , calculated based on testing in accordance with ICC-ES AC70 and ASTM E1190 . Connected components , including wires , must be investigated separately . 2 Multiple fasteners are recommended for any attachment . 3 The concrete thickness at the point of penetration must be a minimum of three times the fastener embedment depth .

1 The tabulated allowable load values are for the powder-actuated ceiling clip assemblies only , using a safety factor that is greater or equal to 5.0 , calculated based on testing in accordance with ICC-ES AC70 and ASTM E1190 . Connected components , including wires , must be investigated separately . 2 Low-velocity fasteners shall be driven to where the point of the fastener penetrates through the steel base material , except otherwise noted . 3 Multiple fasteners are recommended for any attachment . 4 For fastening into 1 / 2-inch or thicker steel , DX460 / DX5 with black cartridge may be needed .
