C9 Stringers & Spools

C9 socket wire stringers and bulk spools in SPT-1 and SPT-2 gauges. From 25-foot pre-cut sections to 1000-foot bulk spools. Available in 12-inch and 15-inch socket spacing. This is the wire that your C9 bulbs plug into for every roofline install.

SPT-1 vs SPT-2

SPT-1 is the standard gauge for most residential roofline runs. Lighter weight. Easier to handle on ladders. SPT-2 is the heavier gauge for long commercial runs where you need to push power further without voltage drop. Pick the gauge that matches your job size and run length.

Pre-Cut vs Bulk Spools

Pre-cut stringers in 25-foot, 50-foot, and 100-foot lengths are ready to install right out of the box. Bulk spools up to 1000 feet let you cut custom lengths on site. Most high-volume installers buy bulk and cut to fit. That eliminates waste and gives exact measurements for every roofline.

Build Your Roofline Setup

Cut to length. Terminate with Gilbert plugs. Pop in your choice of C9 LED bulbs and mount with clips. Need everything in one order? Grab a C9 Pro Light Kit with bulbs, wire, clips, and plugs pre-matched.
