Product Description

500 ft. spool of UL rated CMP/FT6, low-loss coaxial cable for wireless applications, orange LMR 400 Plenum cable. LMR 400 Plenum cable’s flexible conductor enables tight bend radius that works in any install. The LMR 400’s UL tested fire resistant jacket also keeps your space safe from potential hazards.

What is Plenum cable?

Plenum cable has a special fire-retardant jacket that burns at a higher temperature than typical cable. When burned, the cable doesn’t let off toxic smoke that most cables release when burned. These characteristics make plenum cable the safest option to use in any space.

When is Plenum required and who requires it?

Plenum cable is mandated to be installed in any "air handling" space by the National Electric Code. Knowing when a space requires Plenum Cable is very important. One of the easiest ways to do this is to look into the ceiling. If you see a duct going back to the Air Hauler then this means you have a Closed Air System, however if there isn't a duct running back to the Air Hauler then you have an Open-Air System, and this is a Plenum Space and will require Plenum Cable.

Along with these great features, we offer several tools to help you field terminate the cable. This helps because you don't always know exactly how much cable you are going to need until you get to the job site. With these tools you will be able to create custom lengths of cable on the site.
