Drill the holes

Once your hooks are injected you have to drill some holes in order to screw your hooks to the wall.

For this we provide you with an .STL file for a template to drill the holes always in the same position.

In our case we have used 4x30 screws for the wall so we use a 3.5mm drill and a 8.3mm countersink

TIP: Make sure you are drilling straight in the hole
