BESIGN 18AWG 4-Conductor Plenum CL3P Wire 500ft Black

SKU CH-8DZM-RJZDR

18 AWG four-conductor plenum-rated CL3P wire with 16-strand oxygen-free copper for speakers, LED lighting or security alarms in a 500 ft box

  • Less signal loss with 16-strand oxygen-free copper conductors
  • Safe in-wall installation with CL3P plenum fire rating
  • Tangle-free pulls thanks to patented winding and large payout hole
  • Durable packaging with reinforced handles and water-resistant coating
  • Versatile low-voltage use for speakers, LED lighting and security alarms

Low-Voltage Plenum Wire for In-Wall Installations

This 18AWG four-conductor cable carries a CL3P plenum rating and UL listing for safe routing through walls, risers and air-handling spaces in residential or commercial buildings. The black jacket includes a ripcord, foot markers and re-order information for straightforward identification during pulls. It suits speakers, LED lighting, security alarms and similar low-voltage systems that require four conductors.

Oxygen-Free Copper Conductors Reduce Signal Loss

Sixteen-strand oxygen-free copper conductors provide lower resistance and better durability than copper-clad aluminum alternatives. The stranded construction maintains flexibility for easier handling around corners and through tight cavities. No thermal, noise or power-draw data is supplied for this passive cable.

Single 500-Foot Length in a Tangle-Free Box

The product ships as one continuous 500-foot reel packed in a reinforced, water-resistant cardboard box with integrated handles and a patented winding system that prevents kinks during deployment. Installers who need multiple separate lengths or a different conductor count will need additional spools.

Highlights

  • Less signal loss with 16-strand oxygen-free copper conductors
  • Safe in-wall installation with CL3P plenum fire rating
  • Tangle-free pulls thanks to patented winding and large payout hole
  • Durable packaging with reinforced handles and water-resistant coating
  • Versatile low-voltage use for speakers, LED lighting and security alarms

Questions about this item

How do I pull the 18AWG 4-conductor cable from the box without kinks?

Use the massive payout hole and patented winding technology; pull steadily so the ripcord stays inside the jacket and the foot markers remain visible.

What part of this CL3P plenum wire will need replacement first?

The oxygen-free copper conductors are more durable than CCA, so only physical damage to the black jacket or connectors would require replacement.

What is the first limit I hit when running this 18AWG speaker cable continuously?

The 18AWG gauge sets the voltage-drop limit; on long runs the 16-strand oxygen-free copper reaches its current-carrying capacity before the CL3P jacket rating becomes a factor.
