25' C9 (E17) SPT-1 Cords

These 25' cords are manufactured with male and female end connectors. They can be cut to fit. Because they are 20 AWG wire, their maximum run is 2 sets in series.

Do not mix them inline with 18 AWG cords. For instance, do not connect them in series with any of our 50, 100, 500, or 1000-foot cords.
