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’s 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.
