Blocker and jammer
Blockers and jammers keep your ropes (halyards, sheets, bosses, reefs) under tension and prevent them from slipping, even under heavy loads. Indispensable for securing adjustments, they free the winch and make cockpit maneuvers easier. Depending on use, choose a jammer for quick adjustments and moderate effort, or a blocker for more powerful hold and precise control when easing off. Available in single or multiple versions, they adapt to different rope diameters and deck configurations.
