18 AWG SPT-1W Green Zip Cord (Sold by the Foot)

This is the wire behind every custom holiday light display: 2-conductor, 18-gauge green zip cord, cut to exactly the length you need. Snap on slide-on plugs, vampire taps, or C7/C9 sockets and you can build extension runs or light strings that fit your roofline, without a 50-foot cord coiled behind the shrubs. The evergreen jacket disappears into garland, wreaths, and trees, and the stranded copper stays flexible for wrapping and tucking.

It’s called “zip cord” because the two conductors pull apart like a zipper, which makes it easy to separate the ends for a clean connection. The SPT stands for Service Parallel Thermoplastic, and the “W” on this cord means it’s rated for outdoor use. That’s the important part in Vermont, where outdoor displays spend weeks out in slush and sleet.
