Replacement Sockets, C9 / E17, SPT1, Pack of 25, White

Yes — that's one of the two main use cases. Thread these sockets onto SPT1 zipcord wire at whatever spacing you need, then finish both ends with vampire plugs to build a completely custom-length C9 socket run. You can also use a pre-made socket wire spool if you want evenly spaced sockets already on the wire.

Place the socket over the wire so the wire runs through the slot along the socket body. Then press the bottom cap firmly onto the socket — it will click into place and force the wire down onto the internal teeth, which pierce the insulation to make the electrical connection. No wire stripping is needed. The cap can be hard to press on by hand; using a pair of C-clamps or woodworking/welding clamps to apply even pressure makes installation much easier.

The socket itself is the same; the difference is which wire type the socket is designed to crimp onto. SPT1 sockets are made for SPT1 wire; SPT2 sockets are made for SPT2 wire. Always match the socket to the wire type you're using — using an SPT1 socket on SPT2 wire (or vice versa) will not make a reliable electrical connection.

Yes — these are standard E17 base sockets that accept any standard C9 bulb, whether LED or incandescent, screw-in replacement style.
