Re:bus bar thing

Sometimes I can't find the right set of words to google what I'mlooking for (or to find it on Amazon)I'm designing a relay module, with some number of independent SPSTpower relays, and I thought it would be convenient for the customers,if any, to be able to buss one side of some of the relays sometimes.But without soldering.If we had a row of holes on the board, one could bolt down strips ofbuss bar as needed. So I want to buy a flat metal strip with evenlyspaced holes. A customer could, say, snip off a bit with 5 holes andbolt it down with 5 tiny screws to cluster 5 channels.Searching for  buss bar  gets thousands of silly hits.I recall companies that made this sort of thing, electronic pcb busbars, standard and custom. Does anyone know of any?Back in the DIP ics and double-sided board days, we'd sometimes usesoldered-down bus bars for power and ground distribution.Maybe somepeople still do.
