Bulk CAT5 Plenum

What is plenum cable, and do I really need to spend the extra money for plenum rated cat5? Plenum Ethernet cable is required by local fire code in most installations where the cable will be used in plenum spaces (spaces such as air ducts, elevator shafts or some raised ceilings) we strongly suggest you check with your local authorities if this is needed per their codes. CAT5e plenum cable while not truly resistant to fire does not emit the same level of toxic fumes when burning. We offer bulk cat5 plenum rated cable in a variety of common colors. Need plenum cable shielded to offer protection from EMI as well? We also carry bulk 1000 ft shielded cat5 true plenum cable.
