The space above many commercial suspended ceilings doubles as a return-air plenum, and NEC 800.179 requires CMP-rated cabling there. This cable carries the CMP rating with a low-smoke, low-flame-spread jacket — pulling standard or CL2 cable through plenum will fail building inspection in most jurisdictions.
Rated to High-Speed HDMI 1.4 with 10.2 Gbps bandwidth. Carries 4K Ultra HD at 30Hz, 1080p at 60Hz, HDR10, ARC, CEC, and HDMI Ethernet Channel. Heavier 24 AWG tinned copper conductors deliver lower signal loss over the longer cable runs typical in commercial ceiling installs.
Compatible with PS5, Xbox, Apple TV 4K, AV receivers, conference room displays, ceiling-mounted projectors, classroom TVs, and digital signage media players. Quick check: above commercial drop ceiling — Yes; residential in-wall — Yes (or use cheaper CL2); 4K@120Hz — No, HDMI 1.4 limit; runs over 65 ft — use Active or AOC.
24 AWG tinned copper conductors carry stable 4K signal over long passive runs. Foil + braid double shielding rejects interference from HVAC motors, fluorescent ballasts, and other AV cabling sharing the ceiling space. Gold-plated 19-pin HDMI connectors resist corrosion in unconditioned ceiling cavities.
Each cable is sample-tested during production for continuity, signal integrity, and CMP jacket compliance. Manufactured to RoHS environmental standards. If a cable arrives defective or stops working in normal use, Cable Leader handles replacement requests directly — no manufacturer redirects.

Running an HDMI cable above a suspended ceiling that doubles as the building's return-air plenum? CL2 and standard cables violate fire code in those spaces — plenum-rated CMP cables don't. This Plenum-rated High-Speed HDMI cable carries the CMP jacket rating required by NEC for installation in air-handling spaces, where a low-smoke, low-flame-spread jacket is mandatory. Built with 24 AWG tinned copper conductors for stable 4K over long passive runs, foil + braid double shielding, and gold-plated connectors. Compatible with PS5, Xbox Series X/S, AV receivers, ceiling projectors, conference room TVs, classroom displays, and digital signage installs in commercial buildings — does not support 8K or 4K@120Hz; use an HDMI 2.1 fiber AOC for those. Supports 4K@30Hz, 1080p, HDR10, ARC, CEC, and HDMI Ethernet Channel at up to 10.2 Gbps. Best for: commercial above-ceiling installs, conference rooms, classrooms, and any building inspection that requires plenum-rated cabling. Not for: residential in-wall (CL2 is fine and cheaper) or runs longer than 65 ft. RoHS compliant.
