<h2>WICHARD triple pulleys for 8-9 mm rope</h2>
<div class="fiche-txt">These pulleys are suitable for heavy loads and static manoeuvres. The 45 sheave rotates around the stainless steel shaft and is protected by the flanges. The universal head of these pulleys allows a wide choice of attachments. Available with or without balls. Without balls, they are perfect for mainsail hoists, halyards, boom vang, spinnaker sheets for sport catamarans and small keelboats. With balls, they have two rows of lateral balls, which gives them a very good performance under light load. Under high load, the forces are taken up by the stainless steel shaft without lateral friction. You can use them for mainsheet and sheet track, spinnaker sheets and arms, genoa sheets and backstays.</div>
