50 ft Plenum Stereo Cable

The C2G 40518 is a 50 ft plenum-rated 3.5mm stereo male-to-male cable built for commercial and educational audio runs that must meet fire-safety codes for air-handling spaces. Its CMP-rated jacket and foil-shielded 27 AWG copper conductors deliver clean analogue audio without interference in ceiling plenums or wall cavities. Installers who need compliant cable for long-distance stereo connections will find it purpose-built.

Low-Profile Install in Tight Spaces

Low-profile connectors measuring 1.5 inches deep and a 0.25 inch cable diameter allow the assembly to fit inside standard wall-plate boxes and narrow conduit without forcing bends. The solid 27 AWG conductors are stiffer than stranded alternatives, so sharp corners should be avoided during the pull to prevent conductor damage. Terminations are moulded and non-serviceable; verify the run length before cutting any slack.

Analogue Stereo Distance Limits

The 3.5 mm stereo interface carries unbalanced analogue audio, so signal degradation and noise pickup increase with run length even with foil shielding. At 50 ft the cable is suitable for line-level sources such as mixers, paging amplifiers or classroom AV switchers, but not for microphone-level signals or runs that exceed typical commercial ceiling spans. Users needing balanced audio or longer distances should select a different cable type.

FeaturesAudio/video installations in educational and commercial settings often require plenum-rated cabling. Our plenum-rated line was engineered to overcome common challenges faced by installers.
Low-profile connectors (1.5in total depth) save valuable space and enable easier in-wall connections. And our small-diameter (0.25in) cable design further reduces the space and clearance required to run the necessary cabling through walls and plenum air spaces.
This cable is constructed from 24 AWG twisted pair wire with foil shielding to ensure signal integrity in your installation. CMP rating pro

Questions about this item

How can I confirm the 3.5 mm stereo connection is working after routing the 50 ft plenum cable through the ceiling?

Play audio from the source device and listen at the far end; a clear, noise-free signal through the copper conductors and foil shielding shows the link is intact.

What comes with the C2G 40518 cable and what must I supply separately?

The box contains the 50 ft plenum-rated 3.5 mm male-to-male cable with 1.5 in low-profile connectors; you provide the source and destination audio equipment.

When should I choose this 50 ft plenum version instead of a shorter or non-plenum cable?

Select this model when the run must pass through plenum air spaces and the distance between devices is up to 50 ft; the CMP-rated jacket meets building-code requirements for such installations.
