Marketing description

The WIR6CMRGR 1000 ft Cat6 Riser Bulk Cable roll (gray) meets or exceeds all Category 6 specifications to ensure reliable Gigabit network connections, and features a foot-marked jacket that makes it easy to tell how much cable is left on the roll and enables you to measure your cable runs to your exact installation requirements.
This Category 6 cable has been tested for CMR riser installations, and is ideal for in-wall, between floor and elevator shaft cable runs where CMR fire rating is required.
StarTech.com Cat6 cables are manufactured using high-quality copper conductors. While many cable manufacturers offer a "cheaper" cable, based on a copper-coated aluminum core, StarTech.com makes no compromises on quality to ensure you receive top value and performance for your network cable investment.
This Cat6 cable is constructed with 23 gauge copper wire, to support a broad range of Ethernet applications such as Power over Ethernet (PoE). Because StarTech.com uses a high quality copper wire, StarTech.com cables easily sustain the power required for Power over Ethernet applications, whereas the inferior quality offered by copper-coated aluminum cables may be subject to insufficient power delivery, heat buildup, equipment damage and potentially, fire.
