Fast Cat Speaker Wire 14 Gauge 4C - UL Listed, In-Wall 500ft

Our review of the Fast Cat speaker wire 14 gauge 4C finds it best for installers and homeowners who need a reliable in-wall cable for multi-channel audio or security systems; the single biggest reason to buy is its confirmed UL listing with an authentic holographic label that proves compliance and safety for in-wall installations. The cable combines solid oxygen-free bare copper conductors and flexible PVC jacketing so runs are easy to route, and the CL3R/FT4 and CMR flammability ratings give extra confidence when meeting building and insurance requirements.

Key Features

• UL listed with holographic label: The official UL holo tag provides verifiable compliance for safe in-wall installations and peace of mind.
• 100% oxygen-free bare copper: Pure copper conductors deliver stronger, more consistent signal and better conductivity than CCA alternatives.
• CL3R / FT4 / CMR ratings: Multiple flammability and in-wall ratings mean it meets stricter fire and building requirements for residential wiring.
• HighFlex PVC jacket: A flexible outer jacket eases pulling through walls and around studs while remaining durable against abrasion.
• 14 AWG, 4 conductor: Thicker 14 gauge wire and four conductors support multi-room or multi-channel speaker and security runs without signal loss.
• 500 ft bulk length: A long spool reduces joins and gives installers enough cable for larger installations or multiple zones.

Who It's For

The cable is aimed at professional installers, AV hobbyists and homeowners who need a safe, long in-wall run for speakers or security systems and who value documented UL listing and in-wall ratings. Its 14 AWG conductors and four-conductor construction are practical for home theater systems, whole-house audio zones, or multi-camera security runs that demand consistent conductivity.

It is less appropriate for users who need a decorative exposed speaker run (the jacket is white and utilitarian) or those who require extremely thin low-profile wire for tight trim; also, buyers who only need short patch leads may prefer premade speaker cables rather than a 500 ft bulk spool.

Pros & Cons

Pros

• Verified UL listing with holographic label ensures real certification and safe in-wall use.
• Pure oxygen-free bare copper offers better conductivity and a more reliable signal than CCA alternatives.
• High flammability ratings (CL3R, FT4, CMR) make it compliant with many building and insurance standards.
• Flexible jacket simplifies routing through studs and drywall during installation.

Cons

• Bulk 500 ft spool is overkill for simple, single-speaker projects and requires storage space.
• The white PVC jacket is functional but not designed for exposed aesthetic installations.
