Plenum Ethernet Cable

Our plenum Ethernet cable is fire safety rated for use indoors. The CMP jacket is for use in plenum spaces, found above suspended ceilings and below raised floors. It is essential for all cables running through the HVAC area to have the appropriate rating to avoid potential toxic smoke and fire hazards. In most cases, it will be clear when plenum Ethernet cable is necessary by observing local fire codes or insurance requirements. At trueCABLE, we offer high-quality plenum network cable available in Cat5e, Cat6, and Cat6A, as well as shielded or unshielded. Browse and buy plenum-grade network cable below.
