<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>

<h2>Ronstan 20mm Single Orbit Pulley with Lashing</h2>
<div class="fiche-txt">No metal elements in these Orbit pulleys, everything is made of high tech polymer resin capable of supporting high loads. The special feature of the Orbit blocks is also the optimization of the ball track which frees up the central part of the block hub, thus limiting the weight and allowing the lashing to pass through the dyneema garcette. The 20 Orbit series can only be used on dinghy and catamaran trimmers up to 5 meters. Very light and able to support a working load of 250 kilos for a break of 550 kilios for a weight of 9 grams, it is one of the most performing blocks in its category.</div>
