A proper bracket holds the board square, carries the weight through the wall rather than a single screw, and makes lifting the board off straightforward.

That last part is what makes rotation a habit rather than a good intention. Turning a board periodically moves the wear away from the treble twenty and adds seasons to its life, and a mount that makes it a two-minute job is what gets it done.

Slide-in designs keep a disc on the board and the mount on the wall, so the board lifts off without unscrewing anything and seats identically every time it goes back. Getting the height right at fitting matters most — the bullseye sits at 1.73 metres, and a board hung by eye is usually out.
