Nice "job" to spend some cool time with my son together in sunday afternoon...
There is a wall bars (rib stall?) what we need to mount on the wall in his room.
The whole process was around one hour, and he really liked the mounting! ;)
Step 1: Tools
1. 4 x worker hands (2 big hand and 2 small hands)
2. drilling machine and drill bits
3. screws and anchor (hammer)
5. the place where we will mount the wall bars
6. the wall bars
