So to be an accessory: stable, well thought out and easy to assemble. Everything included: spacers and screws range for different screen types, screws, dowels for mounting on masonry or wood. Easy to customize and enough room for corrections in all directions. Genial I found the simple hanging of the device the screen part in the actual wall mount. No fumbling and retching with but the figure is 15 kg screen. As someone has really thought what. Full marks.
