Carry On With Copper

Cu is our standard high quality cable.  We use 6N (99.9999%) pure oxygen-free  copper wire.  The wire is coated in a 7 micron enamel plating to keep it isolated with minimum rigidity and thickness. 

A polyester jacket with matching braided polyester jacket covers the wire.  We use machined aluminum metal shells on the connectors and splitter, and molded ABS tension slider.

The result is a great looking, great functioning cable.  All with great reliability and comfort.
