CMP and CL3P rated — the highest indoor fire safety classification — this 16AWG 4-conductor OFC cable meets code wherever speaker wire passes through air plenum spaces above suspended ceilings or below raised floors where the HVAC system would circulate smoke from a fire.\u003cbr\u003e\u003cbr\u003eRemguard Plenum Polymer insulation and jacket emit significantly less toxic smoke than standard PVC under fire conditions — the material requirement for CMP certification in occupied buildings. At 0.205 in. OD and 22 lbs per 500ft, this is a compact 4-conductor OFC plenum cable, leaving more room in congested plenum spaces where multiple runs share the same ceiling pathway. CMP-rated cable substitutes for CL3R or CL2 in any installation environment.\u003cbr\u003e\u003cbr\u003eStandards: C(ETL)US Listed (Intertek) · CMP\/CL3P · NEC Article 800 · FT6\u003cbr\u003e\u003cbr\u003e• Wire Gauge: 16AWG · Stranded · Conductors: 4 (Black\/Red\/Green\/White)\u003cbr\u003e• Conductor: Oxygen-Free Bare Copper (OFC)\u003cbr\u003e• Insulation: Remguard Plenum Polymer · Jacket: Remguard Plenum Polymer CMP\/CL3P\u003cbr\u003e• OD: 0.205 in.
