50 Pair Telephone Cable (Cat3 PVC/CMR)
Made for riser telephone cabling applications and constructed of 100 24 gauge solid bare copper conductors with a PVC jacket.
This made in the USA cable will qualify for all product-origin specific United States Federal Government sales requirements.
What is Riser Cable (CMR)? Sometimes referred to as PVC.
NOTE: Not all PVC Cable is necessarily Riser rated
Cable which is to be run between floors in non-plenum areas is rated as RISER cable. The fire requirements on riser cable are not as strict. Thus, plenum cable can always
replace riser cable, but riser cable cannot replace plenum cable in plenum spaces. Twisted-pair, coaxial,HDMI and DVI versions of cable are made in plenum and riser versions.

The color coding is very dark and easily distinguished to make for easy punch-down, even in low light conditions. Over the years, this has been the best brand we have sold, due to the build quality, color coding, and compact packaging.
