Shielded plenum security cable, 5 pack. Each roll is 500 feet of 18/4 stranded conductor (18 AWG, 4 conductor) with a white jacket, shielded for noise reduction, and supplied in a pull box for easy deployment. Key benefits Reduces interference: Foil shielding helps protect sensitive signal and lowvoltage power lines from EMI and RFI for clearer camera and sensor performance. Flexible installation: Stranded 18 AWG conductors provide easier pulling around corners and through conduit than solid conductors. Ready for plenum spaces: CMP plenum jacket allows installation in air handling spaces where plenum cable is specified. Long runs with fewer splices: 500 foot pull box length minimizes joints and simplifies routing for typical security and lowvoltage systems. Value and convenience: Five identical rolls let you stage multiple runs, keep spares on hand, or equip several zones without mixing cable types. Clean appearance: White jacket blends with ceilings and walls for discreet installations. Key attributes Configuration: 18/4 18 AWG, 4 conductor, stranded Shielding: Foil shield to reduce electrical interference Jacket color: White Length: 500 feet per pull box, 5 boxes included Package: Pull box for controlled payout and easier handling Intended use: Security and lowvoltage systems requiring shielded multi conductor cable Practical applications CCTV and video surveillance runs where combined power and signal conductors are needed and shielding helps maintain image quality. Access control and door hardware wiring that require multiple conductors for power, lock control, and sensor inputs while reducing noise on control lines. Alarm and sensor networks in commercial buildings, especially when runs pass through ceiling plenums or air handling spaces where plenumrated cable is specified. Installation notes Use standard lowvoltage termination practices for stranded conductors and maintain shield continuity where required. The pull box design reduces twist and stretch during installation and keeps the remaining length protected until needed. Confirm local electrical and building codes for plenum installations and follow practices for grounding the shield if required. This 5 pack of shielded 18/4 stranded security cable provides a practical balance of flexibility, interference protection, and deployment length for multirun security and lowvoltage projects.
