Nippon Labs 20HDMI-3FTMM-C hdmi cable 3 ft 18Gbps CL3

What this cable does and who needs it

The Nippon Labs 20HDMI-3FTMM-C is a 3 ft HDMI 2.0 cable rated at 18Gbps with CL3 certification for in-wall installation. It carries 4K at 60Hz, HDR, 3D and ARC between source and display. The gold-plated male-to-male connectors fit standard HDMI ports on consoles, streamers, projectors and 4K TVs. It suits installers running a short, fire-resistant link inside walls or cabinets.

Installation ease and common pitfalls

The stranded 28 AWG tinned copper construction keeps the cable flexible for tight bends behind equipment or through stud cavities. The CL3-rated PVC jacket meets fire-code requirements for in-wall runs without conduit. A frequent issue is exceeding the 3 ft length when the source and display are farther apart, so measure the exact path before ordering. Another is forgetting that both ends are male; a female coupler is not included.

Check your setup before ordering

Verify that both devices have full-size HDMI 2.0 ports and that 3 ft covers the entire route including slack for strain relief. Confirm the wall cavity allows a CL3 cable if you plan an in-wall run. Ensure the source can output 4K at 60Hz and the display accepts 18Gbps bandwidth for the features you want. This cable does not convert mini or micro HDMI, nor does it add Ethernet or optical audio paths.
