These plenum cable ties meet UL and NEC standards for use in plenum spaces. These ties are effective tools for bundling cables and wire in air handling spaces--above dropped ceilings and below raised flooring, as they won't release toxic gases or excessive smoke upon accidental burning. As such, these ties are also used to secure wiring systems in fire alarms and other safety apparatus. Their distinctive burgundy color lends to safety identification, as well as providing building inspectors with a marker for determining if ties used in air spaces are indeed rated for plenum use.
