Black Box Corporation EYN871B-PB-1000 network ethernet cable Cat6 550 MHz 1000 ft

Bulk Cat6 plenum cable

Black Box EYN871B-PB-1000 is a 1000-foot pull-box of solid 23 AWG UTP copper cable rated for plenum spaces. It meets ANSI/TIA-568-C.2 Category 6 and ISO/IEC 11801 Class E specifications for horizontal runs. The blue CMP jacket uses FEP insulation for fire safety. Installers pull and terminate the bare-wire ends to keystones or patch panels.

Verify plenum rating and solid-core needs

Confirm local code requires CMP-rated cable for the air-handling spaces you are wiring. Solid conductors are not suited for repeated flexing or pre-made patch cords. Ensure your termination tools and connectors accept 23 AWG solid wire. The 1000-foot length suits large projects; smaller jobs may leave excess.

Pull-box convenience and daily handling

The box pays out smoothly and marks every two feet so you track remaining length without guessing. Violet CMP jacket resists flame spread and smoke in plenum areas. Unshielded pairs keep the cable light and easy to route through trays. Cross-member separator maintains pair geometry during pulls. terminado.
