All boards will have two single keyhole hangers on the back of the board. I prefer two so the board will be more solidly connected to the wall and will not be able to swing left and right. If you would prefer only one keyhole hanger at the top like some other dartboards, just send me an e-mail at RightTriangleGames@gmail.com and it's as easy as that.
The keyhole hangers' openings are exactly 12 inches apart so two vertical nails/screws posted 12 inches apart on the wall/door/tree is all you need to do!
Regulation heights of nails/screws so the center of the bull's-eye is the correct 5 ft 8 inch height:
All measurements are from the floor:
Top Screw: 76 1/2 Inches (6 ft 4 1/2 in)
Bottom Screw: 64 1/2 Inches (5 ft 4 1/2 in)
Top of the board: 79 1/2 Inches (6 ft 7 1/2 in)
Bottom of the board: 56 1/2 Inches (4 ft 8 1/2 in)
Set wall screw placement and consistent keyhole placement on every RTG board allows you to switch boards back and forth extremely easily.
Two small screws are barely noticeable. You do not even need to screw into a stud, the board is light enough to hang in the drywall.
Your dartboard will hang 3 inches below the top edge of the board. This is good to know if you are trying to align according to height that would be different than regulation. If you would like these closer to the top or bottom just send me an e-mail. Thanks!
