West Penn Wire 4246EZBK1000 Cat6 Cmr Riser Cable 1000ft

Product Description

The WEST PENN WIRE 4246EZBK1000 is a Category 6 (Cat6) unshielded twisted-pair (UTP) data cable rated CMR (Communications Multipurpose Cable, Riser) and supplied in a 1000-foot pull box. CMR-rated cable meets UL 1666 flame requirements for installation in vertical runs between building floors without the use of conduit in most jurisdictions. This cable is designed for structured wiring installers, low-voltage technicians, and electricians pulling horizontal and vertical backbone runs in commercial and residential buildings. The black jacket color is common in plenum-free riser pathways where color coding by floor or zone is standard practice.

This reel is suited for new construction and retrofit data infrastructure projects where a full 1000-foot box is needed for large-scale runs. Typical installations include vertical riser shafts, telecommunications rooms, server closets, and general office horizontal distribution. The Cat6 specification supports Gigabit Ethernet (1000BASE-T) and 10-Gigabit Ethernet (10GBASE-T) at reduced distances, making it appropriate for high-density network environments with demanding bandwidth requirements.

Key Features

• Cat6 performance rating supports Gigabit and 10-Gigabit Ethernet applications
• CMR (Riser) flame rating meets UL 1666 for vertical shaft installations without conduit
• 1000-foot continuous pull box minimizes splice points on long runs
• Black PVC jacket aids in zone-based color identification in riser pathways
• Unshielded twisted-pair construction for standard structured cabling environments

Compatibility

Designed as a standard Cat6 CMR riser cable compatible with 568A and 568B termination standards at RJ45 keystone jacks, patch panels, and modular plugs used in structured cabling installations.

Installation Notes

Installation should be performed by a licensed low-voltage technician or electrician in accordance with ANSI/TIA-568 structured cabling standards and applicable local building codes. Power down active network equipment before terminating cable ends. CMR-rated cable must not be substituted for CMP (plenum) cable in air-handling spaces — verify the fire rating required by the authority having jurisdiction before pulling cable. Avoid bending the cable below its minimum bend radius and do not exceed the maximum pull tension specified for Cat6 UTP to prevent pair damage.
