This structural timber acts as a distance piece or vertical support within a mine shaft or stope. Studdles are placed between horizontal square sets to maintain spacing and bear compressive loads from the surrounding rock. They are essential for keeping the entire timber framework rigid and preventing the collapse of working platforms.
Make sure the studdle is cut to the exact length so the next set sits perfectly level.
