About this product
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.
Features
Plenum CMP Rated — Code-Compliant for Above-Ceiling Use
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.
4K Ultra HD at 30Hz, 24 AWG Tinned Copper for Long Runs
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.
Works in Conference Rooms, Classrooms, Digital Signage
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, Foil + Braid Shielded, Gold-Plated
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.
Sample-Tested Production — Cable Leader Direct Support
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 50, 100, or 150 feet from media rack to a wall-mounted TV — and copper cables can't carry 4K@60Hz that far without failing? Pure copper HDMI loses too much signal past about 50 ft for clean 4K@60Hz. This 4K HDMI Fiber Optic Active Optical Cable (AOC) carries video over glass fibers, holding the full 4K@60Hz HDMI 2.0 signal over runs that copper simply can't handle. UL Listed with a CL3-rated jacket for code-compliant residential in-wall installation. Built with multi-fiber optical construction, gold-plated HDMI connectors, and a CL3-rated PVC jacket. Compatible with PS5, Xbox Series X/S, Apple TV 4K, AV receivers, wall-mounted TVs, ceiling-mounted projectors, and home theater installs — directional cable: the SOURCE end must connect to the source device. Supports 4K@60Hz, HDR10, ARC, CEC, and HDMI 2.0 features at up to 18 Gbps. Best for: long in-wall home theater runs to far-wall TVs and ceiling projectors. Not for: plenum spaces (use Plenum AOC), 8K, or 4K@120Hz. RoHS compliant.

Running an HDMI cable 35, 50, or 65 feet from a wall-mounted TV down to a media closet — and need it CL2-rated for in-wall installation? This 24 AWG CL2-rated High-Speed HDMI cable is built for long passive runs where lighter 26 AWG cables start losing 4K signal. Built with 24 AWG tinned copper conductors (heavier gauge = lower loss over distance), foil + braid double shielding, gold-plated 19-pin connectors, and a CL2-rated PVC jacket that meets fire safety code for residential and light commercial in-wall installs. Compatible with PS5, Xbox Series X/S, Apple TV 4K, AV receivers, projectors, ceiling-mounted displays, classroom TVs, and conference room setups — for runs longer than 65 ft, use an Active HDMI cable or HDMI fiber AOC instead. Supports 4K@30Hz, 1080p Full HD, HDR10, ARC, CEC, and HDMI Ethernet Channel at up to 10.2 Gbps. Best for: long passive in-wall home theater runs, classroom installs, and conference room cable drops. Not for: plenum spaces, runs over 65 ft, or 4K@120Hz gaming. RoHS compliant.
