Here is one way. Just use the bend deformer on the tube side before a merge.

Oops, I guess I did the opposite of your request.
In that case make sure the box has plenty of subdivision for a nice bend. And make the capture length of the bend equal to the height of the box.

Thank you for answer. I told about different thing ) To bend box and tube on top inherit pos and rotation but doesn't deform. I find a way to make a point on box top and copy tube on it. It's good for simple thing but what if I need a chain? When some part of it deform and some doesn't. In Foundry Modo it's call Spline deformer, and you can just make an influence.

Thank you for answer. I try to achieve this kind of effect. When boxes deforming, but disks doesn't. They only changes their position and rotation, according to box deform. Sorry for my english ))) I hope you understand what I mean )
