/diy/ - Do It Yourself

Hi, i bought a pull up bar (pic related), and i want to instal the heavy bag like in the picture, but i dont want the straps/chains to get twisted.

So my question is if its suitable to connect it with a carabiner-swivel-carabiner?

I'm worried if the weight resistance will not be enough or if you can tell me another details i need to take into account, i will appreciate it.

*I will post more pictures
