These pegs are ment to be screwed in with a #6 wood screw.
I screwed the top pegs into a piece of wood and attached that piece of wood to the wall. The base pegs are ment to be attached to the wall right above the tail of the board. The purpose of the base pegs are to allow the underside of the board to dry after a day of riding and prevent water from running down the wall.
The author marked this model as their own original creation.
