Extron STP22-2P/1000 (part number 22-162-03) — a 1,000 ft plenum spool of two-pair 22 AWG shielded control and audio cable.

The STP22-2P puts two circuits into one plenum-listed jacket, which is exactly what an integrator wants above a return-air ceiling: fewer penetrations, fewer J-hook runs, one inspection. Four 22 AWG tinned copper conductors form two twisted pairs, color coded red/black and green/white, insulated in foamed FEP and wrapped with a tinned copper drain wire inside a full aluminum foil shield. The blue fire-resistant PVC outer jacket carries the NEC CMP listing, and the finished cable measures 0.150 in nominal — noticeably tighter than the non-plenum two-pair equivalent.

Key Capabilities

• Two shielded twisted pairs of 22 AWG tinned copper, 0.030 in (0.76 mm) per conductor.
• NEC CMP plenum listing plus C(UL) 60 °C, approved for air-handling spaces without conduit.
• Foamed FEP insulation with PVC inner jackets and a blue fire-resistant PVC outer jacket.
• Compact 0.150 in (3.81 mm) nominal outside diameter for two full pairs.
• Aluminum foil shield at 100 percent coverage with a tinned copper drain wire; 45 ohms nominal impedance.
• 1,000 ft (304.8 m) self-dispensing spool at 28 lb, with sequential footage markings on the jacket.

Where It Is Used

Ceiling plenums serving corporate floors, healthcare buildings, K-12 and higher-education classrooms, transit terminals and government facilities — anywhere a control link and an audio circuit both need to reach a ceiling-mounted projector, speaker cluster or DSP endpoint under plenum rules.
