The mounting plate to the back of the TV is much too large for small formats, including a 24 "and below. It prevents the connections on my TV 24 '. I had to cut it to size for the power use. Another problem: mounting bracket to the middle. The description is too laconic and almost impossible without using mounting foam placed between the back of the TV and the large fixing screw to keep it in its housing during tightening with the dial. In conclusion, the device is poorly designed and assembly is not properly planned. So I strongly recommend this support to those who do not want tinkering to install.
