Most times it is a hole drilled in the concrete and a sleeve in there or just let the rod drop into the hole.
Fence gate drop rod installation.
Make positional adjustments as required so both drop rods fit into the end of the fence rail.
Close the gate and put the drop rods down the holes in the end of the fence rail.
For equal spacing we recommend the bottom hinge be placed 6 from the bottom gate upright and the top hinge be placed 6 from the top upright.
This is much easier to install on a large gate than a regular locking handle would be because you can make a larger hole to deal with alignment issues.
Hold the 1 2 conduit vertically against the gate and attach the straps.
I used deck screws suitable for treated wood to attach the straps.
If it is bare dirt.
It depends on how hard or easy you want to go about this.
Place hinges at desired position on each gate.
Place the paver with the piece of fence rail down in the hole and make the paver level with the fence rail sticking straight up.
For best results work on a clean at stable surface when mounting hinges to gates.
Either put in some 2 pvc and pour in some cement and put in a sleeve for the bolt to drop into that hole.
I put one strap on the middle rail and one on the lower rail.
