Extron STP20-2P/1000 (part number 22-163-03) — 1,000 ft of plenum-rated two-pair 20 AWG shielded control and audio cable.

This spool is the answer when a job needs both plenum compliance and heavy copper. Four 20 AWG tinned copper conductors are arranged as two twisted pairs, color coded red/black and green/white, insulated in foamed FEP and enclosed by an aluminum foil shield with a tinned copper drain wire. The blue fire-resistant PVC outer jacket carries the NEC CMP listing that lets the run pass through return-air space without conduit, and the larger conductor size keeps loop resistance low on the long pulls a 1,000 ft reel is bought for.

Key Capabilities

• Two shielded twisted pairs of 20 AWG tinned copper, 0.038 in (0.97 mm) per conductor.
• NEC CMP plenum listing with C(UL) 60 °C, suitable for air-handling spaces.
• Foamed FEP insulation, PVC inner jackets, blue fire-resistant PVC outer jacket.
• Aluminum foil shield at 100 percent coverage with a tinned copper drain wire.
• 0.150 in (3.81 mm) nominal outside diameter; 45 ohms nominal impedance.
• 1,000 ft (304.8 m) self-dispensing spool at 30 lb, jacket printed with sequential footage markings.

Where It Is Used

Multi-floor and campus deployments under plenum rules: hospital and clinical AV, airports and rail terminals, corporate headquarters, higher-education buildings, and government or military facilities where control processors and audio endpoints sit far apart above the ceiling grid.
