<h2>Ronstan's range of 40mm Single Orbit Winch 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 reduces the weight. The Orbit Simple Series 40 is a range of blocks in several versions used for mainsheet and spinnaker sheets on dinghies, catamarans and sport keelboats up to 5 meters, but also for halyard, tackle and backstay reefing on boats up to 8 meters. They can also be used for trimming lines on boats over 8 meters. Very light, with a working load of 325 kilos and a breaking strength of 700 kilios, and a compact weight.</div>
