Harken® locking cylinders feature an adjustable mechanical lock threaded onto the rod that physically blocks rod movement and securely fixes its position independent of the boat pressure system. They are commonly used by large cruisers on extended passages to safely lock the rod during pressure release and to act as a safety backup for the hydraulic system.

For pin center length open add stroke length to pin center length closed. Max relief setting is 5000 psi/345 bar. Rod ends (forks) included in weights.
