Fast Cat Speaker Wire 16 Gauge 2C - UL Listed 500ft In-Wall Cable

Our review of the Fast Cat 16 gauge 2C speaker wire finds it best suited for installers and homeowners who need a reliable in-wall audio or security wiring solution. The single biggest reason to buy is the combination of genuine UL listed safety certification with oxygen-free bare copper conductors, which delivers a consistent signal and meets stricter flammability and compliance requirements for internal runs. Installation is straightforward thanks to a flexible PVC jacket that still meets CMR/CL3R and FT4 ratings for building use.

Key Features

• UL Listed with Holo Label: The authentic holographic UL tag provides verifiable safety certification so you can be confident the cable meets national standards.
• Oxygen-Free Bare Copper: Pure bare copper conductors offer higher conductivity and a more reliable signal compared with CCA-style alternatives.
• In-Wall Flammability Ratings: CL3R, CMR and FT4 ratings mean the cable is suitable for in-wall residential and light commercial installations that require fire-safe wiring.
• Highly Flexible Jacket: A pliable PVC outer jacket makes the 500ft spool easier to pull through studs, snake around corners and prep at termination points.
• TAA Compliant: Compliance makes this cable appropriate for projects with procurement rules that require TAA-conforming products.

Who It's For

This cable is ideal for audio installers, AV hobbyists and small business security teams who need a long run of reliable speaker or signal wire for in-wall use. The genuine UL listed label and in-wall flammability ratings make it a practical pick for homeowners replacing or extending wiring behind walls or running cable to speakers and cameras.

Those who should look elsewhere include installers who require shielded cable for high-RF environments or runs longer than typical speaker distances where amplified signal loss must be addressed with different gauges or active solutions. For outdoor direct-burial runs, choose cable designed specifically for exterior exposure.

Pros & Cons

Pros

• Genuine UL listed certification provides verifiable safety compliance for in-wall installations.
• Oxygen-free bare copper conductors deliver clearer, more consistent signal and better conductivity than CCA alternatives.
• Flexible PVC jacket makes pulling through tight spaces and prepping ends fast and simple.
• Long 500ft spool is convenient for larger installs and reduces the need for multiple splices.

Cons

• Not shielded, so it is not the best choice where electromagnetic interference is a known issue.
• White PVC jacket is intended for indoor use and is not rated for direct burial or prolonged outdoor exposure.

Frequently Asked Questions

Is this cable safe for in-wall installation?
Yes. It carries authentic UL labeling and CL3R/CMR/FT4 flammability ratings appropriate for in-wall residential and light commercial use.

Can this wire be used outdoors or buried?
No. The white PVC jacket is intended for indoor, in-wall use and is not rated for direct burial or prolonged outdoor exposure.

How does the conductor compare to CCA wire?
The cable uses 100% oxygen-free bare copper, which provides higher conductivity and a more consistent signal than copper-clad aluminum (CCA) alternatives.
