Ronstan Series 40 Double Block with Becket & Lashing Option
The Series 40 ball-bearing Orbit Blocks™ offer a remarkable blend of strength, efficiency, and durability. They feature renowned dynamic and static load ratings, unmatched in performance block categories. Constructed with lightweight yet robust glass fiber reinforced nylon, they replace traditional stainless steel straps, ensuring superb reliability.
This versatile range includes options for traditional single swivel blocks as well as double sheave configurations allowing for soft attachment systems, which cater to different rigging needs. Capable of handling up to a 12:1 purchase mainsheet system, they are ideal for off-the-beach performance catamarans.
Equipped with our innovative carbon-reinforced C-Cleat™ for secure rope holding, the blocks provide low entry and exit forces, along with fairlead designs that ensure swift adjustments from any angle. With adjustable stainless steel cleat arms, users can customize their preferred cleating angle easily.
Ball Bearing models integrate a 2-stage bearing system designed to reduce friction, utilizing ball bearings combined with a full-contact secondary bearing to allow low friction across the complete working load spectrum.
High Load variants are explicitly tailored for scenarios demanding elevated dynamic or static loads, featuring enhanced durability with high-strength grade 2205 stainless steel sheaves and hubs, accompanied by a triple bearing race to ensure low-friction efficiency at high loads.
