Green winged wire connectors are designed to make electrical ground connections. The contoured wing design provides maximum torque for a variety of electrical applications while the co-polymer shell and live-action spring expand for smooth, progressive tightening providing dependable connections. With a tough, flame-retardant shell that withstands environmental extremes and a long, deep skirt to provide maximum dielectric protection to prevent turned-back strands, they bring comfort and performance at a price that is right.
