This 500' spool of 18 AWG SPT1 zipcord wire is the foundation of a clean, professional Christmas light installation. Cut it to any length you need to build custom extension cords — the same approach used by professional holiday lighting installers to keep every job looking neat and uncluttered, without a tangle of mismatched extension cords in sight.

It also works great for building custom C7 or C9 socket stringers at any length and spacing you need. Combine with our replacement C7 or C9 sockets and slide-on vampire plugs to create a completely custom socket wire run from scratch. Pair it with one of our socket wire spools for large installations where you need both custom socket runs and custom power extension lengths.

SPT1 insulation is the standard choice for most Christmas light applications — lightweight, flexible, and rated for indoor and outdoor use.

Frequently Asked Questions

What is zipcord wire used for in Christmas light installations?

The two most common uses are: (1) building custom-length extension cords so you can run power from any outlet or controller to your display without relying on standard extension cords — this is how professional installers keep every job looking clean; and (2) building custom C7 or C9 socket stringers by adding replacement sockets and vampire plugs at any spacing you need.

What's the difference between SPT1 and SPT2?

SPT1 has thinner insulation and is the standard choice for most Christmas light applications — lightweight and flexible. SPT2 has thicker, heavier-duty insulation, better suited for outdoor applications with higher loads or where extra durability is required. Match the wire type to the vampire plugs and sockets you're using (SPT1 plugs with SPT1 wire, SPT2 plugs with SPT2 wire).

What plugs do I need to finish a custom cord?

You'll need slide-on vampire plugs — available in male, female, inline pass-through, and splicer styles for both SPT1 and SPT2 wire. They press onto the wire without any tools.

Can I use this wire with socket spools to build a full C7/C9 installation?

Yes — this is a very common combination. Use a socket wire spool for your custom-length C7 or C9 socket runs, then use this zipcord wire with vampire plugs to build the custom-length extension cords that bring power from your source to the socket runs. The result is a completely professional, custom-fitted installation.
