1 The tabulated allowable load values are for the low-velocity fasteners only , using a safety factor that is greater than or equal to 5.0 , calculated in accordance with ICC-ES AC70 . Steel members connected to the substrate must be investigated in accordance with accepted design criteria . 2 Low-velocity fasteners shall be driven to where the point of the fastener penetrates through the steel base material , except as noted . 3 Multiple fasteners are recommended for increased reliability . 4 The minimum edge distance for fastening into steel is 1 / 2 ". Minimum spacing for fastening into steel without reduction in performance is 1 ". 5 Noted tabulated allowable load values are based upon minimum point penetration of 1 / 2 " into the steel . If 1 / 2 " point penetration into the steel is not achieved , but a point penetration of at least 3 / 8 " is obtained , the tabulated shear load should be reduced by 8 percent . 6 Noted tabulated allowable load values are based upon minimum point penetration into the steel of 15 / 32 ". 7 Noted tabulated allowable load values are based upon a minimum point penetration into the steel of 1 / 2 ".

1 Allowable load based on a safety factor of 5.0 in direction shown in Figure 6 for attachment of deflection slip clip to 4000 psi Normal Weight Concrete Slab .
2 Allowable load based on a safety factor of 5.0 in direction shown in Figure 7 for attachment of deflection slip clip to 3000 psi Lightweight Concrete Slab with 12 GA . sheet steel pour stop with minimum yield strength Fy = 33 ksi . 3 Testing based on deflection slip clips obtained in February 2007 . Subsequent changes by the manufacturer to the deflection slip clip design may affect load values . 4 Allowable load values are for fasteners installed in concrete having the designated compressive strength at the time of installation . 5 Allowable load values are based off of the fixtures tested . Other members connected to the deflection slip clips must be investigated in accordance with accepted design criteria . 6 Spacing of fasteners depends on the design of each deflection slip clip . Fasteners should be installed through the pre-assigned locations in the deflection slip clip . 7 For base material thickness requirements , reference Section 3.2.1.4 . 8 Allowable values are for loads applied perpendicular to the edge of the concrete . 9 Multiple fasteners are recommended for any attachment . 10 Verticlip is a registered trademark of The Steel Network , Inc .
