I am intended to buy a tv mount which its arm can be extended by buying another unit and using the arm pieces to be added to the 1st unit:http://multibrackets.com/3268.shtml
The nice thing with this model that the arm pieces are modular. I mean you can remove the 2 arm pieces or put one or put two or even more. However the company does not guarantee that it will holds the TV if I put 3 or more arm pieces.
The maximum weight that can be hold with this unit is 25 kg if there is 2 arm pieces (~40 cm arm length from the wall).
My question: If my Tv is 40 inch LED and weights just 10 Kg. Can I extend the length of the arm twice? Since the recommended weight is up to 25 Kg with 40 cm, does that mean with 80 cm arm length I can go up to 12.5 Kg (half the max. weight) without any problem?
I do not know where to ask and it is not easy to get an expert answer. Appreciate any help!
