Facnor standard drum Gennaker furlers are similar in style to headsail furlers but without the aluminum foils. They are equipped with either a shackle or marine eye at the bottom of the drum, and a shackle for securing the tack. Their high load capacity and load-guaranteed design make them a good choice for handling very large sails. They are maintenance free thanks to sealed steel bearings, anodized aluminum drum cheeks and stainless steel rope guide
