Ronstan Series 30 High Load Lashing Orbit Block
Modern high performance and foiling sailboats now experience much higher loads on their control systems. Ronstan’s new 30mm HHL Lashing Block is the perfect solution for these applications.
When world champions choose a product, there is always a good reason. In the case of the 30mm lashing block, World Moth Champion, Paul Goodison, uses it in his vang system because it handles the high loads with low friction, giving him fingertip control. The block, specifically designed for modern high-performance foiling, skiff and multihull classes, suits any applications where high loads are experienced.
Typical applications include high load vang purchase systems on Moth and Lasers, halyards on 16 and 18ft skiffs; cunninghams, outhauls and backstay purchase systems just to name a few.
The RF35109HL has a maximum line size of 8mm and is rated to 550kgs (1210lbs) Maximum Working Load and 1650kgs (3630lbs) 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 42 grams (1.5oz) 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.
Block must be lashed through central hub.
Features:
- Ultra-strong HHL sheave and bearing race: Grade 2205 stainless steel, Balls: Grade 316.
- RF35109HL features class leading dynamic and static load ratings for a 30mm block.
- Frame/cheeks: Glass fibre reinforced nylon.
- Low profile and compact, through sheave becket.
Specifications:
- Max. Rope diameter (in): 5/16
- Sheave diameter (in): 1 3/16
