The particular characteristic of this model is the wide possibility of regulation in height for 14 mms, necessary in the case where, once installed, the floor is dressed again with moquettes, parquet or other. The warranty of operation under prohibitive climatic conditions (-25°c +60°c), thanks to a particular thermostatic oil and the possibility to use a square to measure and/or with interchangeable spindle, both make the S6070 an exclusive product and of great reliabiity. As all the FEV floor springs, the S6070 standard production line is projected with Italian fixed pivot.
