With almost 80% of light sailboats equipped with Series 40 blocks, Ronstan has a strong presence in this market. This historic block has stainless steel cheeks and a double or triple ball bearing depending on the workload required. In parallel, Ronstan has developed a range called Orbit, much lighter with composite flanges and balls on a half-sphere. Combining the best of both technologies: the central bearing and composite cheeks, the new Series 40 is now available on the market.
Lighter and stronger, this range is complete. It goes from the simple block with shackle to the 5 sheaves block allowing to create 12 strands hoists particularly adapted to sport catamarans. An opening block is also available. We will also note the deck block which offers a very neat finish. More than 40 models of pulleys are in the catalog: single, double, triple, with spur, with wedgeâeuros¦! Custom Pinball Balls
In comparison, the single pulley designed for a maximum rope diameter of 10 mm has a working load of 400 kg and a weight of 60 g, while the equivalent in the old range, has a working load of 350 kg for a weight of 70 g. On the price side, it increases a little since the new model is proposed at 30.87 euros HT, against 26.00 euros HT for the old model.
420c Stainless Steel Balls Very suitable for small boats, this new Series 40 can be found on sports catamarans, but also on larger yachts such as the Tricat and Astus trimarans.
