West Penn Wire 25291BBK1000 22 Awg 2C Shielded Plenum Cable

Product Description

The WEST PENN WIRE 25291BBK1000 is a 22 AWG, 2-conductor stranded shielded cable rated for plenum-space installation. It is designed for low-voltage audio distribution and signal wiring in commercial and institutional buildings where air-handling plenum spaces require a CMP-rated jacket. The black outer jacket is suitable for in-wall and above-ceiling runs where fire and smoke ratings are mandated by code. Licensed low-voltage technicians and systems integrators are the primary installers of this cable in structured wiring and distributed audio applications.

This cable is used in commercial audio, background music systems, intercom wiring, and other low-voltage signal circuits routed through plenum-rated air-return spaces. It is well suited for office buildings, schools, healthcare facilities, and hospitality environments where National Electrical Code plenum requirements apply. The 1000-foot spool provides enough run length for large-scale system rough-ins without mid-run splices.

Key Features

• 22 AWG stranded conductors for flexibility during installation in tight spaces
• 2-conductor configuration for balanced or unbalanced low-voltage audio signal runs
• Foil or braid shield reduces electromagnetic interference on signal circuits
• CMP plenum-rated jacket meets NEC requirements for air-handling space routing
• Black jacket color for finished-space and above-ceiling concealment
• 1000-foot spool minimizes splices on long commercial runs

Compatibility

Designed as an OEM-style replacement and standard-stock plenum audio cable for 22 AWG 2-conductor shielded low-voltage signal wiring applications in commercial audio and intercom systems.

Installation Notes

Installation should be performed by a licensed low-voltage or electrical contractor in compliance with NEC Article 800 and local amendments governing plenum-rated communications cable. De-energize all connected equipment before terminating conductors. Avoid sharp bends below the cable minimum bend radius and do not over-cinch cable ties, as either practice can degrade shield continuity and signal integrity. Verify the plenum rating of the installation space before substituting a non-CMP cable in this application.
