Audio/video installations in educational and commercial settings often require plenum-rated cabling. Our plenum-rated speaker wire was engineered to overcome common challenges faced by installers. This wire is constructed from two color-coded 18 AWG twisted pair copper cables (one red one black) to ensure easy identification. The speaker wire is twisted within a naturally colored jacket.Each conductor is made from 7 strands of 26 AWG copper wire. CMP rating provides the fire protection required to run within walls and air plenums without the need for conduit. Wire shows footage markers for easy length tracking.
