This wire is ETL Listed & CL2 Rated which means it is certified for in-wall use. Easily use this wire with banana plugs, spade tips or bent pin applications. It comes wrapped around a hard spool that allows for convenient dispensing, measuring, cutting & storing. A tough, yet flexible insulated jacket around the wire helps to achieve high-quality undistorted sound from your audio equipment. Sequential markings printed directly on the jacket at 3FT intervals give users an accurate & worry-free setup. It’s great for in-home, automotive, auditorium, school, church or business settings. Every do-it-yourself speaker project should start with Mediabridge speaker wires.
