Ronstan's range of 30mm Orbit Single Pulleys
No metal elements in these Orbit pulleys, except for the stainless steel ball bearings, everything is made of high-tech polymer resin capable of withstanding heavy loads. The special feature of the Orbit pulleys is also the optimization of the ball track, which frees up the central part of the pulley hub and thus limits the weight. The 30 Series Orbit Simple is a range of single blocks, flat deck, stand up or suspended, used for mainsail and spinnaker sheets in dinghies, catamarans and sport keelboats up to 5 meters. Very light and withstanding a working load of 300 kilos for a break of 600 kilios for a compact weight, these are all-purpose blocks that are efficient and light for ropes with a maximum diameter of 8mm.

<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>
