Ronstan Series 40 Orbit BB Double Block with Becket and Swivel Shackle

The Ronstan Series 40 Orbit BB Double Block with Becket and Swivel Shackle is a high-performance block that offers exceptional strength, reliability, and versatility. Its class-leading dynamic and static load ratings make it the perfect choice for a wide range of applications. The block features lightweight and durable toughened glass fiber reinforced nylon cheeks, replacing traditional stainless steel straps, to provide optimal performance and reliability.

With a variety of options available, including single swivel blocks, single and double sheave lashing or soft attachment options, and even multiple sheave blocks with quad and quin sheaves, the Series 40 Orbit Blocks offer incredible versatility. They can be used in various systems, including a 12:1 purchase mainsheet system for off-the-beach performance catamarans.

The Series 40 Orbit Blocks are equipped with a carbon-reinforced C-Cleat for secure rope holding with minimal effort. The cleat arms, made from stainless steel, are adjustable, allowing you to set your preferred cleating angle. The blocks also feature fairleads for fast action from any angle.

Ball Bearing versions of the Series 40 Orbit Blocks utilize a 2-stage bearing system, which minimizes friction and ensures smooth operation even under high loads. The High Load versions are specifically designed for applications with high dynamic or static loads and feature a high-strength grade 2205 stainless steel sheave and hub, along with a triple bearing race for low friction even at very high loads.
