If you're not sure what I'm whiffling on about, pop over to rswww.com
and incant "388-2811" into the Search box for an instance of
DIN-rail-mounting commoning blocks, and "220-4131" for ornery DIN-rail
terminals.

I use DIN rail terminals sometimes. One word of advice -- always buy at
least one size up from what you think you might need. Incidently, you
can buy DIN rail boxes, terminal kits (end clamps, earthing terminal,
small assortment of terminals), and sets of 5 or 10 terminals in specific
sizes from many electrical wholesalers, often hanging on display at the
the counter, and this seems to be cheaper than most other places.
ISTR CPC was cheap for the terminals too, but not looked for a while.
