With these cup holders, it is no longer necessary to install cocks on the suction hoses; for this reason, they are recommended in all those cases in which there is a chance that not all the cups come into contact with the load to be lifted (because of an uneven or incomplete load). The actual springing stroke is: - For height C= 55 mm 37 mm - For height C= 110 mm 84 mm
