Hi all,
Good morning and happy new year to all.
I have wire cable railing in my balcony.
I tried to tighten the loose ones but there are some that twist back and stay loose. I thought that the fitting itself is faulty.
I just want to get your inputs if I need to replace the fitting or maybe including the wires.

Thanks guys in advance and have a great day.
Kind regards,
Rohnson
