When your project demands a network cable that meets strict building codes for vertical runs, you need a Cat6 riser cable that delivers both safety and performance. Discounted Cables offers a curated collection of Cat6 riser Ethernet cables, all CMR-rated and ready for installation in non-plenum spaces. You get tax-free delivery anywhere in the USA, fast shipping from multiple warehouses, and a choice of top brands like CommScope, Belden, Genesis by Honeywell, Hitachi, and Quabbin. Every cable in this collection meets or exceeds industry standards, so you can install with confidence and pass inspection the first time.
A Cat6 riser cable, also known as Cat6 CMR, is a network cable designed for vertical installations between floors or inside walls in commercial and residential buildings. The "CMR" designation stands for Communications Multipurpose Cable, Riser, a fire safety rating defined by the National Electrical Code (NEC) Article 800. This rating requires a flame-retardant PVC jacket that prevents fire from spreading vertically through riser shafts or wall cavities.
You use Cat6 riser cable when you need to run Ethernet cable between floors or through vertical spaces that are not part of the building’s air-handling system. The cable’s construction and jacket material ensure compliance with fire codes for these specific zones. All Cat6 riser cables in this collection comply with ANSI/TIA-568.2-D standards, which govern performance, construction, and safety for structured cabling in commercial buildings.
You want to know exactly what you’re installing. Here are the technical details you can expect from every Cat6 riser cable in the Discounted Cables collection:
Conductor: 23 AWG solid bare copper (not copper-clad aluminum)
● Solid copper meets NEC Section 800.179 and TIA standards for in-wall installations
● Delivers reliable performance and supports Power over Ethernet (PoE) applications
Pairs: 4 twisted pairs (8 conductors total)
● UTP (Unshielded Twisted Pair) construction for standard installations
Bandwidth: 250 MHz minimum (many models rated 500–550 MHz)
● Supports high-speed data transmission and future-proofs your network
Data Rates:
● 1 Gbps (Gigabit Ethernet) up to 100 meters (328 feet)
● 10 Gbps up to approximately 55 meters (180 feet)
Jacket: Flame-retardant PVC, CMR-rated
● Prevents vertical flame spread in riser shafts and wall cavities
Length: 1000ft (305 meters) bulk box or spool
● Ideal for professional installations and large projects
Colors Available: Blue, white, black, grey, green
● Supports color-coded network organization
Certifications:
● UL Listed
● ETL Verified
● RoHS Compliant
● TAA Compliant (where applicable)
Additional Features:
● Sequential footage markings for easy measurement
● Compatible with standard Cat6 keystones and RJ45 connectors
● Some models include a spline (cross-filler) for further reducing crosstalk
You install Cat6 riser cable in locations where fire safety codes require a CMR-rated jacket but not the stricter plenum (CMP) rating. Approved installation zones include:
● Vertical riser shafts between floors (the primary use case)
● Inside walls (in non-plenum spaces)
● Conduit runs within buildings (not in air-handling ducts)
● Beneath flooring in non-plenum areas
● General horizontal runs in non-plenum zones
Important: Do not use Cat6 riser cable outdoors, for direct burial, or in plenum spaces (such as HVAC air ducts or spaces above drop ceilings used for air circulation). For those areas, you must use a CMP (plenum-rated) cable to comply with code and ensure occupant safety.
Understanding the difference between CMR (riser) and CMP (plenum) cable ratings is critical for code compliance and safety:
|
Feature |
CMR (Riser) Cable |
CMP (Plenum) Cable |
|
Fire Rating |
Riser (vertical flame resistance) |
Plenum (highest fire safety) |
|
Jacket Material |
Flame-retardant PVC |
Low-smoke, fire-resistant (FEP) |
|
Approved Locations |
Vertical riser shafts, inside walls, non-plenum spaces |
Plenum spaces (air ducts, above drop ceilings), riser shafts, general-purpose |
|
Substitution Rule |
Cannot replace CMP in plenum spaces |
Can replace CMR in riser spaces |
● CMR (Riser) Cable: Use for vertical runs between floors and inside walls in non-plenum spaces. The flame-retardant PVC jacket prevents fire from spreading vertically, but does not meet the stricter smoke and toxicity requirements for plenum spaces.
● CMP (Plenum) Cable: Required for plenum spaces, areas used for air circulation in HVAC systems. The jacket uses low-smoke, fire-resistant materials to minimize smoke and toxic gas emissions in a fire. CMP cable can substitute for CMR, but not the other way around.
Always match the cable rating to the installation zone. Using a CMR cable in a plenum space violates code and creates a fire hazard.
You expect high-speed, reliable performance from your network cables. Cat6 riser ethernet cable delivers:
Gigabit Speeds:
● 1 Gbps (Gigabit Ethernet) up to 100 meters (328 feet)
● 10 Gbps up to 55 meters (180 feet) for high-bandwidth applications
High Bandwidth:
● 250 MHz minimum, with many models rated at 500–550 MHz for extra headroom
Reducing Crosstalk:
● Tightly twisted pairs minimize electromagnetic interference between pairs
● Some cables include a spline (plastic cross-filler) that physically separates pairs, further reducing near-end crosstalk (NEXT) and alien crosstalk (AXT)
PoE Compatibility:
● Solid copper conductors support PoE, PoE+ (IEEE 802.3at), and PoE++ (IEEE 802.3bt)
● You can power IP cameras, wireless access points, and VoIP phones directly over the same cable
Backward Compatibility:
● Works with 100BASE-TX and 10BASE-T networks, so you can upgrade existing infrastructure without replacing all hardware

CMR stands for Communications Multipurpose Cable, Riser. This is a fire-safety rating defined in NEC Article 800. A CMR cable uses a flame-retardant PVC jacket that prevents vertical flame spread. You can install it in riser shafts, inside walls, and other non-plenum vertical runs.
No. CMR cable is not code-approved for plenum spaces. Plenum areas require CMP-rated cable with a low-smoke, fire-resistant jacket. Using CMR cable in plenum spaces violates building codes and creates a fire safety hazard.
You can run Cat6 riser ethernet cable up to 100 meters (328 feet) for 1 Gbps Gigabit Ethernet. For 10 Gbps applications, limit the run to approximately 55 meters (180 feet). Exceeding these distances causes signal degradation.
NEC Section 800.179 and TIA standards require 100% solid bare copper for certified in-wall installations. Copper-clad aluminum (CCA) has higher resistance, underperforms on long runs and PoE applications, and does not meet certification standards. All cables in this collection use solid bare copper.
Yes. Cat6 CMR cables with solid copper conductors support PoE, PoE+ (IEEE 802.3at), and PoE++ (IEEE 802.3bt). Solid copper handles the heat from power delivery better than CCA. You can run IP cameras, wireless access points, and VoIP phones on the same cable.
You need a Cat6 riser cable that meets code, delivers high speed, and installs easily in vertical runs. We give you a complete selection of CMR-rated network cables, all certified and ready for your next project. With tax-free delivery, fast shipping, and expert support, you get the right cable for every riser installation, no compromises.
