CL3-rated (UL certified) in-wall and direct burial oxygen-free copper (OFC) speaker cables are engineered for outdoor, in-wall, and in-ceiling installations, meeting fire-resistance standards for residential and commercial use. The heavy-duty PVC-filled outer jacket is ideal for personal projects, home theaters, commercial audio systems, conference rooms, and entertainment venues. Its direct burial rating permits underground installation without conduit. OFC cables minimize oxidation risk, which can compromise durability and conductivity. This delivers more power to your amplifier, enhances efficiency, and reduces strain on your electrical system, all contributing to superior audio quality and performance from your equipment. CL3-rated OFC cables offer a durable solution. Color-coded insulation on each conductor allows for quick and accurate polarity identification, ensuring precise audio frequency and sound wave transmission from source to speakers. The easy-strip jacket and insulation design simplify splicing and installation. Foot markers provide clear measurements of wire used and remaining length. The UL-certified CL3-rated, PVC-filled jacket withstands voltages up to 300V and offers excellent resistance to crushing and bending. The copper cables are certified as 99.9% pure oxygen-free copper. This cable is also suitable for any low-voltage application needing a two-conductor stranded cable, such as LED lighting or security alarm systems. Each package includes 100-feet (
