Ronstan Orbit BB Triple Block with Becket & Swivel
The Ronstan Series 40 ball-bearing Orbit Blocks™ perfectly balance strength, performance, and reliability. They feature exceptional dynamic and static load ratings in this block size. The lightweight and strong, toughened glass fiber reinforced nylon cheeks replace the traditional stainless steel straps, ensuring optimal performance.
The versatile range includes various options such as single and double sheave lashing, soft attachment possibilities, and multiple sheave blocks with quad or quin configurations. Capable of supporting up to a 12:1 purchase mainsheet system, these blocks are ideal for off-the-beach performance catamarans.
Equipped with a carbon-reinforced C-Cleat™ for secure rope holding, the low friction design allows for effortless operation at any angle. The adjustable stainless steel cleat arms let users set their preferred cleating angle.
The ball bearing models use a unique 2-stage bearing system that reduces friction, along with a secondary full-contact bearing to ensure low friction throughout the working load range.
High Load versions are crafted for applications with expected high dynamic or static loads, featuring a high-strength grade 2205 stainless steel sheave and hub with a robust triple bearing race for low friction under heavy load conditions.
