Sports equipment Master boxing bag and gloves

I have this bag for arround 1 year now but I only used it for like 2 times. In the end wasn't really my thing. It has a base that can be attached to the wall with some drilling but unfortunately no instructions. I have taken several pictures that show what goes where though. Every screw and bolt has been accounted for. There is absolutely no issue with it. It has been hanging for the last year with no problems.
