Leader Cable - 4K High-Speed Plenum-Rated HDMI Cable with Ethernet, 24 AWG CMP for Above-Ceiling Air Plenum Runs - Black HM1

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.
