That’s a wall base for a 65’’ tv. It is a retractable tv mount with full Motion swing out tilt and swivel articulating arm. It can reach a max.
Of 2 meters distance from wall and gives the opportunity to watch tv everywhere in the house, in the living room, the kitchen or even on balcony.
And can carry a max of 100 kg!! What makes it extreme? The fact that even if its fully loaded, it is still completely straightened. It was made of 40x20x3mm hollow sections and 20mm hinges.
Furthermore, a bearing was used for its construction and this makes it easier to move and requires no effort to use.
It was made very quickly for a fun of “make it extreme”.
