Rigid locking in the direction of compression

Locking gas spring HY4
HY4 is the locking gas spring in the direction of compression.

The rigid locking gas spring in the direction of compression Varilock HY4 with tube diameter 28mm is recommended if relatively light applications are loaded with very heavy forces after locking and no flexibility is allowed. A sample application is its use for the tilt adjustment of massage tables and various other types of height adjustments.
