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% 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.
