This is achieved through all-composite reinforced polymer materials and multiple attachment options. Their precision design provides the optimum number of ball bearings for minimum friction while weight reduction is achieved through the use of fibre-reinforced composites in the block head, cleat arms and beckets. Lightweight Kilogram for kilogram of working load BB Orbit Blocks are the world’s lightest. To gain peak performance, we engineered out the heavy steel load straps, head post, shackle and cleating accessories. Through extensive research and development, we replaced virtually all metal components with high-tech polymers and fibre equivalents. Weight and bulk are further reduced in the different block configurations. The ball bearing single and becket block has a through-sheave becket arrangement. The result? The lowest weight possible. Multi-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement. Other brands just link together their single blocks with a heavy steel channel across the top of the block, with unnecessary extra cheeks adding extra weight and bulk not found in Ronstan Orbit Blocks.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHighest working load in its class\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe proven Ronstan 2-stage bearing system (Series 30 and larger) features high compression grade Acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range. The sheave and bearing system is supported by a fibre-reinforced load frame, computer modelled and optimised using advanced stress analysis methods. The Dyneema Link, used in multi-sheave blocks, is produced from high spec SK75 fibre, which is 10 times stronger and lighter than steel, and provides the final connection from the block to the load point. Simple, versatile and secure attachment The single block is easily lashed to an attachment point, and can also accept Dyneema Links and shackles for a variety of efficient attachment alternatives. The Dyneema Link used in multi-sheave blocks is easily fitted and secured by a removable pin. The Dyneema Link can also be removed and replaced by a shackle, custom lashing or strop. These blocks are far more compatible with Dyneema\/Spectra lines, carbon laminate connection points and webbing than traditional blocks with steel loop tops or shackles. Low profile and compact The two way head in the single lashing block allows for alignment at 0° or 90° orientation, while the single swivel block allows for full articulation. The flexible Dyneema Link used in multi-sheave blocks provides 0° or 90° orientation. It connects directly to the head of the block rather than to an intermediate head post. This reduces weight and gives the lowest possible profile while allowing full articulation. Beckets have been carefully designed to minimise height. High performance cleating Ronstan BB Orbit Blocks feature strong, lightweight fibre-reinforced cleat arms optimised at the required cleating angle. Race-proven, carbon-fibre reinforced Ronstan C-Cleats give secure rope holding with low entry and exit efforts, and are fitted with fairleads for fast action from any angle. *RF35100 \u0026amp; RF35100D have stainless steel head posts \u0026amp; shackles.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLightweight.\u003c\/li\u003e\n\u003cli\u003eHighest working load in its class.\u003c\/li\u003e\n\u003cli\u003eSecure, versatile attachment.\u003c\/li\u003e\n\u003cli\u003eLow profile and compact.\u003c\/li\u003e\n\u003cli\u003eUltra low profile thru-sheave becket.\u003c\/li\u003e\n\u003cli\u003eLow friction 2-stage ball bearing system provides consistent performance over the full working load range.\u003c\/li\u003e\n\u003cli\u003eSP versions feature a Nylatron sheave suitable for both rope and wire\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterials:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSheave: High compression strength carbon black Acetal.\u003c\/li\u003e\n\u003cli\u003eBall Bearings: High compression strength Acetal.\u003c\/li\u003e\n\u003cli\u003eFrame\/Cheeks: Toughened, glass fibre reinforced Nylon.\u003c\/li\u003e\n\u003cli\u003eLink: UV stabilised, multi-strand impregnated SK75 Dyneema\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ronstan Sailboat Hardware","offers":[{"title":"Default Title","offer_id":53594330399092,"sku":"RONRF35100","price":24.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/4004\/9524\/files\/RONRF35100-2__34573.jpg.1428984928.jpg?v=1761730267"},{"product_id":"ronstan-series-30-bb-orbit-block-single-slotted-head-post","title":"Ronstan Series 30 BB Orbit Block, Single Slotted Head Post","description":"\u003cp\u003e\u003cstrong\u003eRonstan Series 30 BB Orbit Block, Single Slotted Head Post\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBall Bearing Orbit Blocks boast the highest strength-to-weight ratio available.

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.\u003c\/p\u003e\n\u003cp\u003eTypical 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eBlock must be lashed through central hub.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUltra-strong HHL sheave and bearing race: Grade 2205 stainless steel, Balls: Grade 316.\u003c\/li\u003e\n\u003cli\u003eRF35109HL features class leading dynamic and static load ratings for a 30mm block.\u003c\/li\u003e\n\u003cli\u003eFrame\/cheeks: Glass fibre reinforced nylon.\u003c\/li\u003e\n\u003cli\u003eLow profile and compact, through sheave becket.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMax.
