Viabrico
Why we love it
Exceptional quality and durability.
Convenience in usage.
Wide range of applications.
Main Highlights
VIABRICO Low Voltage Wire : 18/2 gauge black and red speaker wire is ideal for low voltage applications such as 12V/24V DC circuit connections, home or car speakers, home appliances, single color LED light strip, lamps, automotive, boat ect.
Benefits of CCA Wire : CCA 12 volt wire combines the high conductivity of copper with the lightweight properties of aluminum to provide a lighter, more flexible option. It is more cost-effective than copper wire, saving money while providing the same functionality and reliability as copper wire.
Premium PVC Insulation : The PVC jacket of the 18 AWG 2 conductor wire is rugged and flexible, making it suitable for wiring in small spaces. It has good anti-aging, moisture-proof and anti-corrosion properties, and is heat and cold resistant, with an operating temperature range of -20°C to 70°C.
Convenient to Use : 100ft 18 gauge electrical wire length is long enough. Easily peel and cut to any length you need. The 2 colors jacket allow for easy polarity differentiation and are numbered for accuracy, reducing the risk of damage to the device due to incorrect polarity.
Package Includes : The extension led wire comes in 100ft/spool (100ft red and 100ft black) We're committed to top-notch customer service for your pleasant shopping experience. For questions or assistance, contact us directly. Your satisfaction is our priority.
