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 Superior Essex, CommScope, BERK-TEK, trueCABLE, and Wavenet. 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. To earn the CMR listing, the cable must pass the UL 1666 flame test, which burns the cable inside a simulated vertical shaft and confirms the fire does not climb from floor to floor.
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 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:

● 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) on single runs, or about 37 meters (121 feet) in tight bundles

● 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) that cuts crosstalk even further
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). Plenum spaces call for CMP (plenum-rated) cable, while outdoor and underground runs call for an outdoor-rated or direct-burial jacket.
You need to understand the difference between CMR (riser) and CMP (plenum) cable ratings for code compliance and safety:
|
Feature |
CMR (Riser) Cable |
CMP (Plenum) Cable |
|
Fire Rating |
Riser (vertical flame resistance) |
Plenum (highest fire safety) |
|
Fire Test |
UL 1666 (vertical shaft test) |
NFPA 262 / UL 910 (tunnel test for flame and smoke) |
|
Jacket Material |
Flame-retardant PVC |
Low-smoke PVC or 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. A CMR cable in a plenum space violates code and creates a fire hazard.
Fire ratings follow a strict order: CMP sits at the top, followed by CMR, then CM or CMG, and finally CMX. You can always substitute a higher-rated cable for a lower one. So, if you already stock riser cable, Cat6 CMR works anywhere code allows general-purpose CM cable, such as horizontal runs within a single floor. However, CM and CMX cables lack the flame resistance for riser shafts, so never use them for floor-to-floor runs.
You expect high-speed, dependable 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) on single runs for high-bandwidth applications
High Bandwidth:
● 250 MHz minimum, with many models rated at 500–550 MHz for extra headroom
Crosstalk Control:
● Tightly twisted pairs minimize electromagnetic interference between pairs
● Some cables include a spline (plastic cross-filler) that physically separates pairs, which further cuts near-end crosstalk (NEXT) and alien crosstalk (AXT)
PoE Compatibility:
● Solid copper conductors support PoE (IEEE 802.3af), 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, a fire rating defined in NEC Article 800. The cable passes the UL 1666 vertical shaft flame test, so 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, such as HVAC air ducts or open areas above drop ceilings. These spaces require CMP-rated cable with a low-smoke jacket. A riser cable in a plenum zone fails inspection and creates a fire hazard.
No. A standard CMR jacket has no UV or moisture protection, so it breaks down in sunlight, rain, and soil. For outdoor runs or direct burial, choose a cable with an outdoor-rated or gel-filled jacket built for those conditions instead.
You can run Cat6 riser Ethernet cable up to 100 meters (328 feet) for Gigabit Ethernet. For 10 Gbps, keep single runs under about 55 meters (180 feet), or about 37 meters (121 feet) in tight bundles. Longer runs cause signal loss.
Yes. Fire ratings follow a clear order: CMP, then CMR, then CM or CMG, then CMX. A higher rating can replace any lower one, so a Cat6 riser cable works wherever code calls for CM or CMG cable, though never in plenum spaces.
Copper-clad aluminum (CCA) has higher resistance, runs hotter under PoE loads, and fails TIA certification for in-wall networks. Solid bare copper carries data and power without those problems, which is why every cable in this collection uses 100% copper conductors.
Yes. Cat6 CMR cables with solid copper conductors support PoE (IEEE 802.3af), PoE+ (IEEE 802.3at), and PoE++ (IEEE 802.3bt). You can power IP cameras, wireless access points, and VoIP phones over the same cable that carries their data.
Choose Cat6 when your runs need Gigabit speeds or short 10 Gbps links. Choose Cat6A if you need full 10 Gbps performance across the entire 100-meter channel, or plan for Wi-Fi 7 access points. Cat6 costs less and installs more easily.
Check the outer jacket. Every compliant cable prints its fire rating, such as CMR, along the jacket at regular intervals, together with the brand, category, and listing mark. If the jacket shows CM or CMX only, the cable is not riser rated.
