West Penn Wire 25810NT0500 RG-8 Plenum Coax Cable 500 Ft

Product Description

The WEST PENN WIRE 25810NT0500 is a plenum-rated RG-8 coaxial cable supplied in a 500-foot length. Designed for shielded signal transmission, this coaxial cable carries RF and low-level analog signals in installations where fire code requires plenum-rated wiring. The plenum jacket rating makes it suitable for routing through air-handling spaces and open ceiling plenums without the need for conduit. Electricians and low-voltage communication installers specify plenum-rated coax wherever NFPA 90A or local codes mandate reduced smoke and flame spread in supply and return air spaces.

This cable is intended for use in commercial and residential installations where shielded coaxial signal runs pass through plenum air spaces, dropped ceilings, or HVAC supply areas. Typical applications include antenna distribution, RF signal runs, and low-voltage communication wiring in buildings subject to strict fire and smoke ratings. The 500-foot quantity accommodates longer trunk runs without mid-run splices.

Key Features

• Plenum-rated jacket meets fire and smoke requirements for air-handling space installation
• RG-8 coaxial construction provides shielded signal transmission
• 500-foot continuous length reduces splice points on long runs
• Sold as a single unit (EA) for straightforward order quantities

Compatibility

Designed as an OEM-style drop-in replacement and standard specification coaxial cable for plenum-rated shielded coax applications in commercial and residential low-voltage signal systems.

Installation Notes

Installation should be performed by a licensed electrician or qualified low-voltage technician in accordance with NFPA 70 (NEC) Article 820 and applicable local codes governing coaxial cable wiring. De-energize any connected signal or distribution equipment before terminating cable ends. Avoid sharp bends below the cable minimum bend radius, and do not route alongside high-voltage conductors without maintaining proper separation per code. Confirm the plenum rating meets the specific air-handling space classification required by the authority having jurisdiction before installation.
