Levelling elements for fixing to the ground with base in black glass fibre reinforced polyamide-based technopolymer, threaded AISI 304 stainless steel articulated stem with adjusting hexagon and option of having it without no-slip disk or with SBR rubber no-slip disk fixed to the base.
The fixing is carried out by means of two 180° holes, closed by a diaphragm (removable with an awl) to prevent the deposit of unsanitary residues if not used.
