The Ronstan Series 30 Ball Bearing Orbit Block™ Triple with Becket & Cleat delivers the highest strength-to-weight ratio available in its class. All-composite fibre-reinforced polymer construction eliminates heavy steel components, achieving the lowest possible weight without compromising load capacity. The proven Ronstan 2-stage bearing system — high compression acetal ball bearings combined with a secondary full-contact bearing — provides minimum friction across the full working load range.

The race-proven carbon-fibre reinforced C-Cleat™ offers secure rope holding with low entry and exit effort, fitted with a fairlead for fast action from any angle. The ultra-low profile through-sheave becket minimises height, and the Dyneema® Link provides simple, versatile, and secure attachment — easily replaced with a shackle, custom lashing, or strop. SP versions feature a Nylatron® sheave suitable for both rope and wire.
