I made some skadis boards with my cnc, so I don't have wall attachments.
use 4 single mounts for a talova skadis, or the double version to fix the ends of 2 skadis boards by drilling the wall only once
Put the mounts on the board, line it up on the wall and mark the wholes using a small screwdriver, through the holes in the Skadis. Remove the mounts, screw them into the wall and then remount the boards
