With pure copper conductors, integrated shielding, and UL 910 plenum certification, this cable delivers superior conductivity and EMI rejection for audio distribution, control circuits, and low-voltage signaling in above-ceiling and HVAC return environments.
Whether you’re installing a distributed audio system in a commercial auditorium, retrofitting a building automation network, integrating alarm circuits in a healthcare facility, or deploying control wiring in a modern smart building, plenum-rated bare copper cable ensures pristine signal transmission and absolute code compliance. The convenient 1000ft pull box eliminates tangled spools, reduces on-site setup time, and provides single-handed cable dispensing—keeping your crew productive from arrival to completion.
Key Features & Benefits
- Fire-Rated Plenum Construction – UL 910 and NFPA 262 certified for return-air plenums, above-drop ceilings, and mechanical spaces. Burns at extremely low rates with minimal smoke and toxic gas emissions—protecting occupants and meeting every major building code (NEC, IBC, NFPA).
- Pure Bare Copper Conductors – 100% copper core provides maximum electrical conductivity and signal clarity. Ideal for audio, video, alarm, and low-voltage control applications where impedance consistency and signal fidelity are non-negotiable.
- Integrated EMI Shielding – Multi-layer shield design blocks electromagnetic interference from power equipment, wireless networks, and RF sources. Maintains signal integrity even when routed near HVAC systems and power distribution.
- Stranded Construction for Flexibility – 22 AWG stranded design allows superior bend radius and tight routing around structural obstacles. Professional-grade construction handles the mechanical demands of installation and cable management.
- Professional Pull-Box Packaging – 1000ft arrives in ergonomic pull box with single-handed dispensing. Eliminates kinks, cuts setup time, reduces waste, and simplifies on-site cable management for every installation.
- UL-Listed & Code-Compliant – UL 910 certification ensures your installation passes inspection without compromise. Building officials and electrical inspectors immediately recognize plenum rating—no callbacks, no rework.
- Long-Run Signal Reliability – Bare copper maintains impedance consistency across extended runs (500+ feet). Superior conductivity minimizes signal loss in audio and high-frequency control applications.
- Bulk Efficiency – 1000ft spool maximizes coverage per order, reducing per-foot material costs versus shorter spools. Convenient for multi-floor buildings and distributed system installations.

Frequently Asked Questions
Q: What’s the difference between bare copper and insulated conductors?
A: Bare copper provides maximum electrical conductivity and impedance consistency—ideal for audio and signal-critical applications where signal clarity matters. Insulated conductors are used in applications where circuit separation or safety isolation is required. Check your application manual to determine which is appropriate.
Q: Is this cable suitable for audio applications?
A: Yes. Bare copper conductors are excellent for audio—maximum conductivity with minimal impedance shift. Verify your amplifier output is safe for unshielded conductor connections; this cable’s shield protects against EMI but is not for safety isolation.
Q: Can I use this for in-wall installation?
A: No. This cable is plenum-rated (above-drop ceilings) only. For in-wall applications, use wall-rated (CMP) cable with proper jacket. Plenum rating is specific to return-air spaces—do not substitute for wall installation.
Q: What’s the minimum bend radius?
A: Stranded construction allows bends to approximately 1.5–2 inches minimum radius. For extremely tight runs, verify local codes don’t require larger bend radii.
Q: How should I store the pull box before installation?
A: Keep indoors in a dry environment (50–90°F ideal). Protect from direct sunlight and extreme humidity. Plenum jackets are durable but benefit from controlled storage conditions. Unopened spools remain stable for 2+ years.
Q: Does this come with connectors or termination hardware?
A: No. This is bare conductor cable. Connectors (barrier strips, RCA, XLR, or terminal blocks) are ordered separately based on your application. Most audio and control equipment accepts standard connectors for stranded conductors.
Q: What’s your return/warranty policy?
A: Full 30-day money-back guarantee on unused, factory-sealed spools. All cable carries a 1-year manufacturer’s defect warranty covering conductor integrity, fire-rating compliance, and performance specifications.
Q: Can I order different lengths?
A: Yes. We offer 500ft pull boxes and custom lengths. Contact sales for availability and pricing on shorter runs or alternative specifications.
Q: Is this cable compatible with my existing system?
A: If your current system runs 22/2 cable, this is a direct upgrade with enhanced bare copper benefits. Verify with your equipment manual that bare copper connectors are acceptable (most audio and control systems are).
Q: How long is shipping on in-stock items?
A: In-stock items ship within 1–2 business days. For bulk orders or custom lengths, contact sales for lead time and volume pricing options.
