Winmau Edge Corner Dartboard Bracket

Not exactly 90 degrees on the brackets. So the board leans more to one side. Also the holes in the brackets do not line up to any studs. Making the drywall anchors bear the entire weight of the board. Which is not ideal. The weight of the board causes the provided anchors to come loose. Which then makes the board sag and wiggle around. In order to improve on this issue o had to drill 4 more hole in the brackets about a 1/2 inch from the corner. That way I could drill the entire system into the studs of the wall. As long as the board is pushed all the way back in the support tube it doesn’t seem to pull the screws out of place. Almost perfect
