Installation Tips
1.Use a rotary hammer for 1/2" holes — hammer drill struggles at this diameter
2.Minimum edge distance: 2-1/2" (5× diameter)
3.Minimum anchor spacing: 5" (10× diameter)
4.Always verify concrete thickness — minimum 3-3/4" for shortest anchor
5.For seismic SDC D-F, specify ductile wedge anchors per ACI 318-19 §17.10
