Meyer Komfortballast KB V 1.0 FS17
Meyer comfort ballast KB Pack
At any weight, you can choose whether you want to let mount a hook.
At the big weight you can also mount an extra weight.
It’s all configurable.
In real life you can hook up things (for example a chain or something).
in the FS the hook has unfortunately no function. It’s just decoration to make it look more realistic.
