Product Description

Features: 1) They are composed by two gas springs which the F1 strength value are different 2) Under static pressure, they have the barometric pressure damping forces 3) Under dynamic pressure, they have the dual damping forces of barometric pressure and the hydraulic pressure 3) Suitable for support devices which F1 strength values are little, the ranges of variation of the compression forces are large, and cushions are needed in the compressing process
