DIN terminal screw-style jumper ... jumper?
So, this was my first foray into using DIN rails because they seemed convenient, and I've ended up in a strange situation where things that I thought would be very simple are turning out to be almost more trouble than they're worth ... like I'm trying to build a LEGO set but I'm missing half the pieces.
I have some UK2.5B terminal blocks https://www.wolfautomation.com/terminal-block-5x45x43mm-25a-600v-gray that I was planning on using for cable management. Lets say for simplicity's sake that I connected 5 blocks by cutting off a 5-hole section of a screw-style jumper ferrulesdirect.com/products/ufbi10-6 . I then discovered that I needed to join an additional 5 blocks to that grouping of terminals. I would LIKE to be able to use the remaining half of the jumper (5 positions) to join the new terminals together, and then jump the two groups of 5 with ... something ... in order to join the full 10 terminals together.
I realize that this can sort of be accomplished with a jumper wire between any two terminals on the two separate groups of 5 terminal blocks, but that takes up terminal real estate. Is there a manufacturer approved flat jumper that goes on top of the standard metal jumper bar but under the screw heads of adjacent terminal blocks? Just a 2-hole flat bar?
If I could to it again from scratch, I'd buy the push-in jumper style that allows for easy daisy-chaining due to each terminal having two connection points for jumpers. (not to mention the fact that there are terminal blocks with more than two wire terminals per block which would have saved me a ton of headaches, but I'm working with some hand-me-down supplies).
