TV wall bracket too strong for my use!

This bracket is very robust, the joints are hard, the brakes would need to be slightly nuts loosened see grease the axes ... I returned the product because its weight is almost equal to that of my TV 32 "(7 , 5 kg for 11 kg!) and my walls are dubbing (I do not think the ankles hollow walls are sufficient given the cantilever and handling guidelines) ... I think this support is . suitable for large televisions and set on a concrete wall Personally I advise against it for the walls lined unless doing masonry work ... Positives: robust and multi directional.
PS: for the Amazon service "I will have one day!", Until then no worries!
