C2G Plenum-Rated 18AWG Shielded Speaker Wire

Overview

The C2G 29207 is a plenum-rated speaker wire designed for audio and video installations in educational and commercial settings. It comes in a 500-foot bulk length, providing ample cable for extensive runs. The wire features two color-coded 18 AWG copper conductors twisted together to reduce interference and simplify installation by clearly identifying positive and negative leads.

Its plenum-rated CMP jacket allows safe installation in air plenums and inside walls without additional conduit, meeting strict building codes. The 100% foil shield combined with a stranded copper drain wire ensures proper grounding and reliable audio performance. Footage markers printed along the cable help installers measure and cut precise lengths, minimizing waste and speeding up the setup process.
