My experience is limited there, but every patch cord I've taken apart has

I did not know that. Thanks. So it's solid wire and keystones. (and any holes I drill don't have to accommodate the connectors. )
I have had reasonable luck installing "keystones" (rj45 plugs) on
stranded patch cables and I have also purchaced MANY ready made cables
with solid conductors. (often for about the cost of the connectors
alone, for up to 25 ft of cable - The joys of china "dumping" product
