10 Pack Shielded Plenum Security Cable, White, 18/4 (18 AWG 4 Conductor), Stranded, CMP, Pullbox, 500 Feet Overview A readytoinstall set of plenumrated security cables supplied in ten 500 foot pullboxes. Designed for reliable signal transmission in commercial and institutional plenum spaces where a shielded, flexible 18 AWG 4 conductor cable is required. Key benefits Plenumrated construction (CMP) for use in air handling spaces where plenumrated cable is required. Shielding reduces electrical interference and crosstalk for clearer signal transmission in security and lowvoltage systems. Stranded 18 AWG conductors provide flexibility for routing through conduit, trays, or tight bends without compromising conductivity. Packaged in pullboxes for easier oneperson pulls and reduced risk of kinking or tangling on the job. White jacket for a clean, professional appearance and easy blending with ceilings and walls. What this cable solves Minimizes signal degradation in environments with fluorescent lighting, motors, or other electrical noise. Simplifies installation in plenum air spaces by matching building code plenum requirements for lowvoltage wiring. Reduces labor time and material handling issues through preboxed 500 foot lengths and stranded construction. Technical highlights Quantity: 10 pack of pullboxes Length per pullbox: 500 feet Conductor: 18/4 (18 AWG 4 Conductor), stranded Shield: Shielded for noise protection Jacket color: White Rating: CMP (plenum) Suitable for lowvoltage security, data, and control wiring Compatible uses and applications Access control and door entry systems in commercial buildings where plenumrated cable is required. CCTV and security sensor cabling within ceiling plenums and above suspended ceilings. Lowvoltage wiring for alarm, intercom, and control panels in office buildings, schools, and healthcare facilities. Installation notes Use standard lowvoltage termination practices for 18 AWG stranded conductors. Route and secure cable according to local codes for plenum spaces and follow device manufacturer wiring recommendations. Test continuity and shielding at both ends before concealing cable behind ceilings or walls. Why choose this configuration The combination of shielded conductors, stranded 18 AWG flexibility, plenum CMP rating, and 10 factory boxed 500 foot lengths makes this cable suitable for large installations and retrofit projects where reliable, codecompliant lowvoltage wiring is needed.
