Well I can share this much. Everything I used was US manufacture from US companies. I had no choice. Everything that went into the end product which went out the door was US manufacture, also no choice. Watched endless films on national security every month too.It is unfortunate that we as a society have become so dependent on Chinese products. It's not just simple matter of economics either. There are hidden costs that come along with it.
We have no control over the quality nor safety of these products (think smeltered electronics). They skimp so much that nothing in general is very durable. And pouring money into their tech industry, how can that not be a detriment to national security?
We should really rethink our policies on this. Subsidize some of those industries if we have to. We need to take our manufacturing back.
So we are saying no Chinese made din rail?
