This mount is designed for LCD VESA standard screens with a screen size from 10\" to 23\" and weight up to 15kg. The BT7513 has a twin arm design that allows for full flexibility when mounting your screen - it can mount the screen flat to the wall or extend out to up to 450mm from the wall. There are three swivel points - one at the wall for 180º, one in the middle of 240º and one at the screen of 240º - this makes it possible to mount your screen in the most inconvenient of locations such as in corners. The BT7513 also has a tilt function of up to +/- 17º.
