This should have worked with my shielded CAT-7 cable but didn't. and keystone jacks to prevent static electricity. Second, those connectors with 26 AWG wire didn't make a good connection. I must have made over a dozen. I finally got my hands on some shielded connectors and plugs from Cable Makers and they were very basic in comparison and required no tools other than wire cutters. This required a $37 crimping tool.
