Constructed with all-composite reinforced polymer materials, this orbit block features multiple attachment options to ensure versatility and secure connections. Its precision-engineered design incorporates the optimal number of ball bearings, significantly reducing friction for smooth operation while maintaining a lightweight profile. The use of fiber-reinforced composites in the block head, cleat arms, and beckets results in a durable yet lightweight component suitable for demanding marine environments. This orbit block is suitable for control lines, halyards, vangs, and backstays on sailboats up to 16 feet, providing reliable performance in both racing and cruising contexts. The sheave is made from high compression strength carbon black Acetal, ensuring durability under load, while the frame and cheeks are crafted from toughened, glass fiber-reinforced nylon for added resilience. The link is UV stabilized and impregnated with multi-strand SK75 Dyneema, offering excellent resistance to environmental factors. Its compact, low-profile design minimizes obstruction on the deck and ensures efficient handling of control lines. With a maximum working load of 990 pounds and a breaking load of nearly 2,000 pounds, the Ronstan Series 30 Orbit Block is a dependable choice for sailors seeking lightweight, high-performance hardware for their rigging systems.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eLightweight design with high strength-to-weight ratio\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMaximum working load of 990 pounds (450 kg)\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSecure, versatile attachment options\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLow profile and compact for minimal deck obstruction\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePrecision ball bearings for minimal friction\u003c\/li\u003e\u003c\/ul\u003e","brand":"Ronstan","offers":[{"title":"Default Title","offer_id":44529340317738,"sku":"55177","price":40.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/55177XL.jpg?v=1783071652","url":"https:\/\/atticusgoods.com\/products\/ronstan-series-30-double-ball-bearing-orbit-block-for-sailboat-rigging","provider":"Atticus Goods","version":"1.0","type":"link"}
