This installer's box of stranded 22/10 copper wire came from my old job as an alarm technician/installer. The footage is marked on the wire, and it runs from #7966 to #8376, or about 410 feet. It is gray, and rated CM/CL2, meaning it is rated for interior of walls, etc., for communication and low voltage applications, less than 150v. It could be used for anything low voltage from camera systems, train sets, projects, or its intended use of alarm systems and control circuits. The box looks rough because it has been sitting on my garage shelf for 20 years. Purchased new, this wire costs on average $2.75 per foot, which would be $1127 for this box. It's a good deal.
