Monoprice SlimRun Cat6A S/STP Ethernet Network Patch Cables are designed for high performance 10G environments. SlimRun Cat6A S/STP is much thinner and lighter than standard Cat6A shielded cables. The 36AWG flexible cable and snagless narrow boot design is easier to install/uninstall and takes less space than conventional 23 or 24 AWG Cat6A shielded cables. Monoprice Ethernet cables are made of 100 percent pure bare copper wire, as opposed to copper clad aluminum (CCA) wire, and are therefore fully compliant with UL Code 444 and National Electrical Code TIA 568 C.2 fire and safety standards, which require pure bare copper wire in communications cables.
