The self-leveling head is an additional element of the pedestal head, consisting of two spherical-shaped components. The terrace pavers rest on the head's corner. Before laying the last fourth paver, you can adjust the height using the nut on the pedestal to achieve the desired terrace level.
Once the pavers are installed and you walk on the terrace, the self-leveling head is only loaded vertically, ensuring it doesn't change its position.
