The Rotation Unit is a clever solution that allows you to switch elegantly between portrait and landscape view. It needs to be screwed to the back plate of the mount to allow the tablet wall mount to rotate by 90°on the wall.
The Rotation Unit is compatible with Companion Wall for iPad 10.2"/10.5", Companion Wall for Samsung A8 10.5", Dame Wall for iPad 10.2"/10.5" and Dame Wall for iPad 10.9"/11".
