Perfect for an HDMI cable in a sheath

I used this adapter to connect my receiver to my TV home cinema.
I had a cable "LCS - 5M - Type D HDMI Cable - HDMI to HDMI Micro - Version 1.4" in diameter sheath in a 20mm plasterboard wall (3m). A conventional HDMI does not pass through a sheath diameter 20mm.
With this adapter, I end up with a cable HDMI Type A / Type A HDMI
it works very well for a decent price (much cheaper and easier to implement than HDMI wall outlets - but it is less aesthetic).
