"5 STARS!!! Exactly what I needed for my project. Great prices and fast deliver" - Jon B - MD

Cables with a Plenum, or CMP jacket are needed when they are run in ceilings or through crawl spaces. This conforms to many local fire codes. They are also used in Digital Lighting Management Systems, to control lighting fixtures remotely. There is a lot of jargon and different jacket type ratings, but to be safe always look for CMP on the jacket. This is the highest level of in-wall and in-ceiling rated plenum wire. The reason why these are required is because it burns slower than regular Riser Rated Cable in case of a fire. All plenum cables manufacturered and sold by are 350Mhz rated, the fastest speed achievable! Although CMP may not be a better quality cable than CMR, it is better to be safe when running new installations or just wiring existing environments. Please note that all plenum cables are built to order in 1-2 days and cannot be returned.
