LOW-PROFILE CONNECTORS  The depth of the connectors (1.5 Inches) allows the cable to be put into tight spaces such as wall plate boxes SMALL DIAMETER  The small-diameter (0.25 Inches) cable design further reduces the space and clearance required to run the necessary cabling through walls and plenum air spaces 28 AWG CONDUCTOR WITH FOIL SHIELDING  The solid conductor creates flawless transmission of your audio signals as the foil shielding protects and prevents the cable from unwanted noise interference that can disrupt audio signals and degrade audio quality PACKAGING  To ensure you receive the highest quality products, C2G packages all product in C2G branded packaging
