When you are running cable through plenum airspaces and need smooth payout from a large reel, this Wavenet Cat6 plenum cable on Reelex II is worth looking at. It comes as part number 6E04UPXX4N with a thousand feet of 23 AWG solid bare copper on an unshielded twisted pair design rated up to 600MHz. The CMP and FT6 listings cover you in drop ceilings and ducts, while TIA-568-C.2 verification and RoHS compliance check the performance boxes. Inside the jacket, FEP insulation handles heat better than standard polyethylene, a separator keeps pair geometry intact, and a ripcord makes stripping straightforward. The Reelex II spool pays out without tangling, which matters when pulling long distances or working with multiple reels. You also get nine jacket colors including black, green, orange, and yellow alongside standard options, so organizing circuits by color is easy. Whether wiring a data center, hospital, or multi-story office, this spool delivers code-compliant performance with less hassle.
