Designed for highly loaded control systems, it performs exceptionally well on mainsheet and spinnaker sheet systems, running backstays, halyards, and all maneuvers requiring minimal friction.<\/p>\n<p class=\"isSelectedEnd\">Its efficiency relies on high-performance, low-friction bearings featuring a central cage that keeps the Torlon\u00ae rollers perfectly separated and aligned. This design ensures smooth sheave rotation even under heavy loads, while reducing wear and energy loss.<\/p>\n<p class=\"isSelectedEnd\">The shackle offers great installation versatility with three possible positions: locked parallel to the sheave, locked perpendicular to the sheave, or free to rotate. This last configuration prevents rope twisting and optimizes line performance.<\/p>\n<p class=\"isSelectedEnd\">Black Magic Air blocks are therefore a preferred choice for sailors seeking reliable, lightweight, and high-performance equipment capable of meeting the demands of offshore sailing and competition.<\/p>\n<p class=\"isSelectedEnd\"><strong>Technical specifications Wichard Black Magic 75\/57 fiddle block:<\/strong><\/p>\n<ul data-spread=\"false\">\n<li>Ultra-lightweight, high-strength construction<\/li>\n<li>Low-friction bearings for maximum efficiency<\/li>\n<li>Torlon\u00ae rollers kept parallel for improved performance<\/li>\n<li>Excellent load-handling capabilities<\/li>\n<li>Adjustable shackle with multiple locking positions<\/li>\n<li>Ideal for sheets, halyards, running backstays, and high-load control systems<\/li>\n<li>Working load: 2,268 kg<\/li>\n<li>Rope diameter: 14 mm<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>The <strong>Wichard Black Magic 75\/57 mm<\/strong> fiddle block is designed for high-performance sailing applications.
