Basketball Rim above garage - unusual placement

[landoa]

Hello,

We will add a basketball backboard/rim above the garage. Its high quality and heavy (not quite 100 pounds altogether)...

Here's a detail of the wall extender. The 4-bolt side normally attaches directly to the wall ...

However, the front wall of the garage is not high enough for the rim to be at standard height (3m).

So, we plan to create a vertical extension of the wall, from the back side (above the waterproofed level)...

... using hollow steel rectangular tubing (2.5 cm x 2.5 cm).

Two tubes will be attached horizontally and directly to the wall and two vertical tubes will attach on top of the horizontal ones and extend 25 cm above the wall.

The wall extender, that came with the backboard, will attach to the vertical tubes.

Would it be better to bolt all the way through the 12 cm wall? Or could I get away with Fischer FBN 8/50 bolts?

I might even add some vertical reinforcement with these L-shaped steel corners. Don't want the backboard bending in the wind, do we?

If nobody dunks on this, can we build it to last a few years?

Thanks for any advice to ensure this is doable and solid!

The top horizontal rail fixings will fail. Then the bottom rail fixings will fail.

Put a post in the ground.

Hello,

Thanks for your reply.

Why will the rail fixings fail? They are rated to support up to 600kg.

Otherwise, we could bolt all the way through the wall. Would that fail too?

Best regards

The fixings will be ok but the uppermost masonry wont. Unless its reinforced concrete?
