RONSTAN Series 30 Orbit Triple Block with Becket and Cam
Lightweight and strong blocks for modern rigging systems.
The 30mm triple blockwith becket and cam cleat features thinner cheeks between the sheaves reduces weight while separating lines and is ideal for Mainsheets, boom vangs, backstays, halyard tuning systems, Cunninghams and other systems that are not cleated remotely.
Ronstan’s goal for the Orbit Blocks™ was to produce a block with the highest strength to weight ratio—and they nailed it. Through extensive computer modeling unnecessary metal components were replaced by engineered light-weight composites without compromising strength. The unique glass fiber reinforced nylon cheeks and head design can be secured using the supplied loop or converted to a soft attachment using a Dyneema® link to further reduce weight.
Performance was not lost with the weight savings. In fact the Orbit Blocks™ have the highest working loads in their class and feature an improved two-stage bearing system that efficiently handles static and dynamic forces throughout the load range. High compression grade acetal orbital ball bearings migrate to the loaded area of the sheave to handle light to moderate loads; larger loads are shouldered by the full-contact PTFE impregnated nylon bearing with carbon fiber reinforcement. Conventional and high-tech lines run smoothly over the UV resistant acetal sheave
Sailors can have the best of both worlds with Ronstan Orbit Blocks™. These lightweight and compact bocks are smooth, efficient even under larger loads and are an ideal solution for modern control line systems on dinghies up to larger yachts.
