Superior Essex 77-246-21 Cat6 Riser Cable Cmr Cmx Blue

Product Description

The SUPERIOR ESSEX 77-246-21 is a Category 6 riser-rated (CMR/CMX) unshielded twisted pair (UTP) network cable designed for structured cabling installations in commercial and residential buildings. Built to Cat6 performance standards, this cable supports high-speed data transmission and is suitable for use in vertical runs between floors. The blue jacket color aids in cable identification during installation and post-installation management. Low-voltage electricians and data cabling technicians are the primary installers of this product type.

This cable is intended for in-wall and between-floor riser pathway installations where a CMR or CMX fire rating is required by local building codes. Typical applications include horizontal and backbone runs in office buildings, schools, healthcare facilities, and multi-unit residential buildings. The 1000-foot pull box format is standard for new construction and large retrofit projects where bulk cable is pulled through conduit or open plenum pathways rated for riser use.

Key Features

• Cat6 performance rating supports Gigabit Ethernet and high-bandwidth data applications
• CMR and CMX dual fire ratings meet riser installation code requirements
• 23 AWG 4-pair conductor configuration per TIA-568 structured cabling standards
• Blue jacket for straightforward cable plant identification
• 1000-foot pull box format reduces handling time on large cable runs

Compatibility

Designed as a standard Cat6 riser replacement or new-install cable compatible with RJ45 keystone jacks, patch panels, and modular plugs rated for 23 AWG Cat6 termination.

Installation Notes

Installation should be performed by a licensed low-voltage technician or electrician in accordance with NEC Article 800 and applicable local codes governing communication cable riser installations. Power down active network equipment before terminating cable ends. Avoid exceeding the cable bend radius or pulling tension limits specified by the manufacturer during fish and pull operations. Do not install CMR-rated cable in plenum air-handling spaces where CMP-rated cable is required.
