Barre transversale sans fil Sphere

Hello, We just installed the rod and draperies. We have it extended to approx. 145”. It looks great but is somewhat unstable, especially when moving the draperies. Is it possible to get 2 more support brackets and hardware to make it more stable? Thank you.

This curtain rod is very sturdy and glides easily. I would definitely buy it again for another project. The curtains I used were very light weight. I do not believe this rod would be the best choice for a heavy curtain since the clips are not that big.
