Monoprice SLIMRUN CAT6 UTP ETHERNET PATCH CABLES are designed for high density environments where space is a premium. SlimRun's ultra‑slim 0.149‑inch diameter 28AWG cable and narrow boot design reduces congestion and simplifies moves, additions, and changes. SlimRun Cat6 is component tested, which provides a better level of performance over channel‑rated patch cables. 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 TIA‑568‑C.2 fire and safety standards, which require pure bare copper wire in communications cables.
