<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>
