Save the time and hassle of building Ethernet cables by using fixed-length UTP Cat6 Ethernet Network Cables from Monoprice! The FLEXboot Series of cables feature a thinner cable boot protecting the plug retaining clip, which makes it much easier to depress the clip and protective cover. 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 (NEC) TIA-568-C.2 fire and safety standards, which require pure bare copper wire in communications cables.
