Strip the wires at both ends to expose them, being careful not to damage the wire or leave any bare copper exposed. If you’re connecting to an existing wire, use wire connectors to secure the new wire to the old one. Then, thread the new wire through any holes or conduits and secure it in place using cable ties or clamps.

Make sure to secure the wire with a knot so that it doesn’t come loose during installation. Once the wire is in place, start winding it around the spool, taking care to wrap it tightly and evenly. When you’ve finished winding the wire, secure the end with another knot and trim off any excess.

Finally, attach the spool to the wall or other surface using screws or other appropriate hardware. By following these steps, you can ensure a safe and secure installation that will provide reliable performance for years to come.
