CMR — Communications, Riser
Rating: Riser Rated | Standard: NEC: Article 800, UL 1666 | CEC: Section 60, CSA FT4 | CSA: C22.2 No. 214
Rated for vertical runs between floors in commercial buildings. Limits flame spread in shafts and risers better than CM, CMG, CL2, or CL3 cables. Can substitute for all of those grades in any application. The solid mid-tier default for commercial LED installs.
Moss LED Use Cases
- Multi-story building LED facade installations
- Vertical cable runs feeding floor-by-floor LEDs
- Elevator shaft and stairwell LED accent lighting
- Convention centers and arena riser spaces
- Default for permanent commercial LED installs when unsure
Cable Type Quick Decision Guide
Not sure which grade to specify? Start here:
- Residential or basic in-wall LED runs? → CL2 or CL3
- Canadian project or CSA compliance needed? → CMG
- Vertical runs between floors in a building? → CMR
- Above drop ceilings or air-handling spaces? → CMP
- Internal fixture or driver wiring during manufacturing? → AWM
Pro Tip
When in doubt on a film or TV set, CMR is a solid default for most permanent installs. For temporary stage builds and location shoots, CL3 is usually sufficient. AWM is only for internal fixture wiring during manufacturing — never for field runs. Always verify with the location's fire marshal or AHJ (Authority Having Jurisdiction) before installation.
Reference guide only. Always consult NEC/CEC codes, local AHJ, and a licensed electrician for your specific installation. Cable substitution rules per NEC 725.154 and 800.154.
