Side Net Extensions (Spornia Golf Nets Only)

The net extension is a great accessory. Very easy to Install.

I think I attached the side net extensions correctly, but the video was too short to see what they should look like at the end. The close-up was nice, but when you're done how should they appear? My net is on concrete, so I have the tail ends being held by bricks.
When I have the sides stretched out they are not taut, and are kind of flimsy. Not the material, the material is fine. It's the engineering, or, I did a poor job of attaching and setting them up. I was hoping for maybe something like the roof extension. That works great, very stable, stays in place.
If anyone has any suggestions for my sides I'd love to hear it.

My son and I were hitting in the garage and one of us broke the one 2ft by 2ft in the whole room by missing the net...with the side net in place, no issues sense! Super easy to install and can be pulled back and held in place with little weight!

Really like my net. Easy to put up and take down quickly.
