The height-adjustable pedestals from the RAPTOR series are based on the so-called wedge technology, consisting of a lower and upper wedge. Height adjustment is achieved by sliding the upper wedge relative to the lower one along the notches (steps). Once the desired height is reached, the RAPTOR pedestals, loaded with the weight of the terrace, cannot change their height either upwards or downwards. Height adjustment could only occur due to significant vibrations or oscillations that could move the terrace structure, or in the case where the terrace experiences tension causing certain parts to lift.

In contrast to other solutions for leveling terraces using wedge pedestals, our RAPTOR pedestals have special openings where screws can be inserted to permanently connect the lower and upper wedges.

We recommend connecting the wedges with screws if the phenomena described above may occur, especially in non-standard areas and rows of pedestals along the terrace edge. However, this is not mandatory and should be left to the decision of the terrace installer.
