Built for durability and designed with installers in mind, our 500' C9 SPT-1 spool delivers reliable performance season after season. Featuring 12" socket spacing and heavy-duty 18 AWG wiring, this spool is perfect for creating custom holiday light runs.
What sets this cord apart is the new collar socket design, engineered for superior water resistance and longevity.
- Precision-molded top lip forms a tighter seal around the bulb, reducing the risk of water intrusion and corrosion.
- Four-channel drainage system—two side vents plus two rectangular base drains—prevents pooling and speeds up drying.
- Rectangular drains break surface tension more effectively than traditional circular holes, eliminating the “water bubble” effect.
The result: a longer-lasting, professional-grade cord that’s easier to maintain and keeps displays shining bright all season.
