Locking Cylinders

Locking Cylinders

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. In addition, 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 cylinder’s mechanical lock is engaged, limiting the stroke for sailing.
