Conductors are unchanged from the standard SPK 14: one pair of bare copper at 14 AWG apiece, with the raised strand count Extron applies across the SPK range so a thick cable still handles well. The difference sits in the jacket, which is rated for the air-handling spaces above a ceiling grid. Extron cautions that its plenum bulk cable is approved for North America and is not certified across most of Europe, so check regional approvals before you specify it.\u003c\/p\u003e\n\u003ch3\u003eKey Capabilities\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePlenum-rated SuperFlex jacket for return-air pathways\u003c\/li\u003e\n\u003cli\u003eOne pair of bare copper conductors, 14 AWG each\u003c\/li\u003e\n\u003cli\u003eSequential numbering printed along the jacket for measuring on site\u003c\/li\u003e\n\u003cli\u003eListed as a 500 ft (152 m) spool rather than the full 1,000 foot reel\u003c\/li\u003e\n\u003cli\u003eExtron's current SPK 14 plenum listing is SPK14P\/1000, part 22-155-03\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhere It Is Used\u003c\/h3\u003e\n\u003cp\u003ePlenum-space loudspeaker runs in schools, universities, hospitals, corporate offices and public buildings, where local code requires a plenum-rated jacket in any void that carries return air, and where the heavier 14 AWG conductor suits the run length.\u003c\/p\u003e\n\u003ch3\u003eSpecifications at a Glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eConductor gauge: 14 AWG\u003c\/li\u003e\n\u003cli\u003eConductors: two, bare copper, one pair\u003c\/li\u003e\n\u003cli\u003eJacket: SuperFlex, plenum rated, sequentially numbered\u003c\/li\u003e\n\u003cli\u003eSpool length as listed: 500 ft (152 m)\u003c\/li\u003e\n\u003cli\u003eExtron part number: 22-155-02\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAvailability note: Extron's current SPK 14 part number table shows only 1,000 foot spools, so this 500 foot plenum put-up is a legacy configuration — confirm with Ampronix before ordering.
