Voltive 14/2 Shielded Riser Cable (CL3R) 500 ft
Voltage rating, shielding, and rated pathways matter for in-wall installations. This Voltive 14/2 Shielded Riser cable uses 14 AWG stranded bare copper conductors with an aluminum and Mylar foil shield plus a drain wire, enclosed in a white jacket. The OFC (oxygen-free copper) conductors help minimize signal loss and improve durability. It is CL3R rated for riser installations (between floors) in both residential and commercial buildings, and UL Listed for safety and reliability. A 500-foot box provides ample run capacity for long projects.
Why it stands out:
- Shielded construction with drain wire helps minimize EMI/RFI
- CL3R fire-safety rating suitable for in-wall and riser use
- OFC conductors for better signal integrity and durability
Voltive 14/2 Speaker Wire (UL Listed, CL2/CL3) 500 ft
This bulk speaker wire is designed for both in-wall and outdoor/underground routing. It features 14 AWG, two conductors, and an OFC core, wrapped in a black jacket. The wire is UL Listed for CL3 and direct burial, making it versatile for home theater runs, outdoor speakers, and commercial installations. The oxygen-free copper ensures reduced resistance and better signal clarity across longer runs. The 500-foot pull box minimizes interruptions on larger projects.
Key points:
- OFC conductors to minimize signal loss
- CL3 + Direct Burial rating for flexible indoor and outdoor use
- UL Listed for safety and reliability
14 Gauge 50ft Shielded Wire (WIDFDXDRE) 2 Conductor
Compact shielded cable designed for precision electronics and small-to-mid scale deployments. This 50-foot shielded 14 AWG 2-conductor wire uses pure copper conductors and a double shielding layer (aluminum foil plus braided copper), providing strong EMI/RFI protection. Insulation and jacket materials aim for durability in automotive, 3D printing, CNC, VFD spindles, and other signal-critical applications. Ratings indicate 300V and 80°C, with a robust resistance profile and grounding support via shielding.
Important aspects:
- Double shielding to suppress interference
- 100% OFC conductors for improved conduction
- Suitable for sensitive electronics and industrial systems
Voltive 14/2 Speaker Wire White 500 ft (Riser Rated)
This white jacketed 14/2 speaker cable is designed for in-wall and riser installations, carrying a CL3R rating for fire safety compliance in multi-story buildings. The OFC conductors reduce signal loss and help sustain audio quality across runs. It remains UL Listed for safety, and its 500-foot box is ideal for professional installations or large projects requiring long pulls without frequent splices.
Highlights include:
- Riser-rated CL3R construction for in-wall use
- 400+ foot continuity potential in large installations
- OFC conductors for improved sound transmission and durability
Custom Cable Connection: 14 AWG Plenum Shielded 100ft
Designed for commercial environments that require plenum-rated cabling, this 14 AWG shielded 2-conductor cable is offered in a 1000t spool, suitable for ventilation-safe ductwork routing. Shielding supports EMI/RFI suppression, and the plenum rating makes it appropriate for air-handling spaces in building infrastructure. While primarily used for security and data systems, the shielded construction also benefits high-fidelity audio runs that pass through plenum spaces.
Considerations:
- Plenum-rated for air handling spaces
- Shielded design reduces interference from HVAC and other equipment
- 1000t spool minimizes the need for frequent reordering
Buying Guide: Key Purchase Considerations
When selecting a shielded 14/2 cable, consider the following factors to align with project needs and safety standards:
- Shielding Type and Effectiveness: Aluminum foil, braided copper, or layered shielding improve EMI/RFI suppression. For sensitive electronics, double shielding or shielded jacket designs may be preferable.
- Conductor Material: Oxygen-free copper (OFC) offers lower resistance and higher durability than copper-clad aluminum (CCA). OFC often comes with a price premium but can deliver clearer signal integrity over longer runs.
- Jacket Material and Color: White jackets are common for in-wall use and visibility, while black jackets are typical for speaker and outdoor applications. Jacket color can aid identification on a job site but does not affect performance.
- Rating and Compliance: CL3R for risers and CL3 for general in-wall use are common. For direct burial, look for outdoor/direct burial ratings. UL listing is a good reliability signal.
- Voltage and Temperature Ratings: Ensure the cable’s voltage rating (commonly 300V) and temperature tolerance (often up to 80°C / 176°F) match the application environment.
- Length and Packaging: Bulk 500 ft or 1000 ft spools reduce connectors and spills on large projects. For shorter runs, 50 ft or 30 ft options may be more convenient.
- Application Suitability: In-wall, riser, direct burial, or plenum-rated cabling dictates which product is appropriate. Direct burial requires robust outdoor ratings, while plenum ratings are essential for spaces in HVAC shafts.
- Vibration and Shielding Demands: For sensitive audio, video, or control signals, higher shielding levels can protect against EMI from nearby equipment or power lines.
- Cost vs. Benefit: OFC cables typically come at a premium. Weigh the expected signal integrity improvements against budget constraints and run length.
In summary, for in-wall and riser installations, CL3R-rated shielded cables with OFC conductors provide a sound balance of safety and performance. For outdoor or direct burial scenarios, look for direct burial or outdoor-rated variants. For high-end audio or data-sensitive projects, double shielding and plenum-rated options may offer additional protection and compliance.
