Bel Cat6 and Cat6a Plenum Patch Cords are ideal for Ethernet network connections that require patch cords to run through plenum space above dropped ceilings or under raised floors. The Plenum jacketing on these Bel patch cords is coated with flame retardant. Bel Cat6 and Cat6a Plenum Patch Cords are also built using special plastics that resist sweltering and the spreading of toxic fumes in the case of a fire. Plenum-rated patch cords should be used in any plenum space for these reasons. These Plenum patch cords have standard RJ45 plugs on each end, equipped with snagless boots to protect the RJ45 clip during pulls through tight locations. Bel Plenum patch cords are available in both Cat6 and Cat6a performance levels.
