Installation Tips
1.Drill the hole the same diameter as the anchor — 3/8" bit for 3/8" anchor
2.Minimum 5 diameters from edge (1-7/8") — capacity reduces at tighter spacing
3.Minimum concrete thickness: embedment depth + 4× diameter (3.75" for 2-1/4" embed)
4.Cannot be removed once set — plan your layout carefully
5.Use HDG or stainless for exterior or wet locations
