Modern high performance and foiling sailboats now experience much higher loads on their control systems. Ronstan's new 20mm HHL Lashing Block is the perfect solution for these applications. The RF25109HL has a maximum line size of 6mm and is rated to 300kgs (1980lbs) Maximum Working Load and 900kgs (1980lbs) Breaking Load. The Breaking Load is dependent on the strength of the lashing through the central hub. The hub can also double as a becket take off point. Such a high load rating is unique for a block of this size. At just 14 grams (0.5oz) its impressive strength-to-weight ratio is a result of clever design and the selection of the right materials, such as glass fibre reinforced nylon cheeks, a high-grade stainless-steel sheave, ball race and balls. Typical applications include high load vang purchase systems on Moth and Lasers, cunninghamsand outhaul purchase systems just to name a few.
