Thanks to its compact, low-profile design, it can accommodate several halyard leads in a small area, optimising the organisation of manoeuvres on deck. Its dimensions of <strong>L: 97 mm; W: 32 mm and H: 95 mm<\/strong> and its weight of <strong>326 g<\/strong> are major advantages of this block.<\/p>\n<p>Made with a hard-anodised aluminium sheave, this block offers increased <strong>resistance to high loads<\/strong> and wear from repeated friction. Its high-strength bearing system is based on a <strong>PTFE<\/strong> composite bearing and side bearings. This ensures smooth, reliable operation, even under high transverse loads.<\/p>\n<p>The rounded cheeks are specially designed to limit premature halyard wear. This extends rope life and ensures smooth operation. With a maximum working load of <strong>2273 kg<\/strong> and a breaking load of <strong>4545 kg<\/strong>, this block is designed to withstand high forces, meeting the needs of cruising and racing yachts.<\/p>\n<p>With its four fixing points, it guarantees robust and secure installation on deck or at the foot of the mast, using <strong>8 FH mm screws<\/strong>.
