What Is a Plenum Cable?
Plenum cable is made with a jacket intended for installation in air-handling spaces, such as certain spaces above drop ceilings. Cable requirements depend on the installation and local code. Check the cable's printed rating and your project specifications before ordering. The Belden 1695A SDI cable above is CMP-rated; if your XLR project calls for a specific printed certification, contact us to confirm the available construction.
