Ronstan Series 40 Orbit BB Triple Block with Becket & Swivel
The Series 40 ball-bearing Orbit Blocks™ are engineered for exceptional strength and reliability while maintaining lightweight design. With class-leading dynamic and static load ratings, these performance blocks are ideal for a variety of marine applications.
Constructed with toughened glass fiber reinforced nylon, these blocks replace traditional stainless steel straps, achieving a perfect blend of performance and durability. The versatile design includes options for single and double sheave lashing, plus multiple sheave blocks capable of handling a 12:1 purchase mainsheet system, making them ideal for off-the-beach performance catamarans and more.
Equipped with Ronstan’s carbon-reinforced C-Cleat™, these blocks ensure secure rope holding with minimal entry and exit effort, complemented by fairleads for quick adjustments from any angle. The adjustable stainless steel cleat arms allow for customized cleating angles.
Ball Bearing versions utilize a 2-stage bearing system to reduce friction, while High Load models feature a high-strength grade 2205 stainless steel sheave and a triple bearing race for optimal performance under high loads.
