How to install above the rim basketball hoop system

push on the back board up to get it to lock. Use the catch plate to bring it down.

The locking teeth or retention spring, if equipped may be damaged and blocked.

I would contact the manufacturer.

Should have a union in center of post.

I would clear any loose debris, repack around pole with a dry concrete mix then add water to it make sure pole is level, brace if necessary and give 24 hours to set up.

Your either going to have buy a new one which I'm sure you want to be a plan Z. With that said, your going to have to weld it at a position that is not adjustable or is possible weld and screw 2 sides where it can move at the broken angle

You need to give us a better picture and description of your problem. It looks like you are working with a basketball goal that is laying down on the ground. Do you really mean only the "Net," or are you using the word net to mean the whole backboard mechanism? Are you talking about hooking the strings of the net to the orange "hoop?"
Is this the first time you have tried to raise it, or has something changed after you have used it successfully for awhile? Is this new and you put it together yourself? If so, you probably made a mistake. Review the instructions, or ask a mechanical friend to look at it.
Often the answer is easy - its asking the right question that is the hard part! Hopefully you can understand that you have not yet asked us the right question.

Unfortunately, I couldn't find a manual or instruction guide online. Here is the contact page of the Rawlings website. They should be able to help you assemble it.

Here is a link to the manual you are looking for. I found it on the manufacturer's official site.
