<h2>Ronstan's range of 30mm Orbit Single Pulleys</h2>
<div class="fiche-txt">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.</div>
