The Spinlock ZS Open Jammer for 18–24 mm lines is a mobile high-load jammer and an essential tool for peeling spinnakers and headsails and for reefing. Spinlock calls it unbeatable in an emergency: it acts as a line clamp if a winch or other hardware fails, or if a halyard jams, a riding turn forms or a line is damaged. It also frees up a winch during a sail change.
