Installation Notes

This riser-rated cable is designed for vertical installations between floors in non-plenum spaces, such as riser shafts, elevator shafts, and vertical cable runs in walls. The CMR rating ensures the cable meets fire safety requirements for these applications. The aluminum mylar shielding protects against electromagnetic interference, making it ideal for installations near electrical equipment or in electrically noisy environments. Always consult NEC Article 725, 760, and 800 requirements and local building codes before installation.
