How to fit a hole to the length of the ankle.
Place the dowel next to the drill used to drill.
Make a mark by sticking a colored adhesive around the drill.
Draw the marks of the various holes to be drilled with the help of a spirit level.
Drill by guiding the adhesive.
When it reaches the wall, the hole is at the desired depth.
Finally, insert the dowels into the holes that have been drilled to the correct size!
Use a drill with a diameter corresponding to that of the ankle and adapted to the nature of the material to be drilled (concrete, wood, brick, plaster...).
