b'Locking CylindersHarken locking cylinders feature adjustable mechanical locks threaded onto the rod to block rod movementAdjustable lock prevents rod and securely fix its position independently of the boats pressure system. They are commonly used by largemovement during pressure release.cruisers on extended passages to safely lock the rod during pressure release and as a safety backup for the hydraulic system. A long-stroke cylinder is often used during the mast stepping process to lean the mast forward and hook up the furlers. After commissioning, the cylinders mechanical lock is engaged, limiting the stroke for sailing.
