RONSTAN
Series 55 Orbit Block Accessories

The ultimate, next-generation, high-performance blocks incorporate unique innovations including radically new bearing systems, super light, all-composite materials, innovative new head fittings and a sleek design for the highest strength to weight ratio available. The precision design provides the optimum number of ball bearings in critically loaded areas, eliminates them in inactive areas and reduces ineffective mass, creating the "2-stage" bearing system for durability and low friction performance. The flexible Dyneema® rope link is a product of the latest trends in grand prix ocean racing and provides a more flexible, lighter weight and lower profile solution than traditional shackles. It can be set at a 0 or 90 degree orientation, provides stress-free articulation without allowing the block to over-rotate, and is locked in place with a security clip that doesn’t require tools to fit. The Dyneema link is also more compatible with carbon, Dyneema and webbing connection points than steel loop tops or shackles.
