Ronstan Series 30 Ball Bearing Block Single Becket Option Lashing

Series 30 Ball Bearing Block Single Becket Option Lashing. Ball Bearing Blocks boast a high strength-to-weight ratio through composite reinforced polymer materials and multiple attachment options. Precision design provides the optimum number of ball bearings for minimum friction while weight reduction is achieved using fibre-reinforced composites in the block head, cleat arms and beckets. Proven 2-stage bearing system with high compression grade Acetal ball bearings and a secondary full-contact bearing for minimum friction across the full working load range. The sheave and bearing system is supported by a fibre-reinforced load frame, computer modelled and optimised. Dyneema Link is used in multi-sheave blocks as a high-spec SK75 fibre connection. Simple, versatile and secure attachment options including lashing, Dyneema Links and shackles. Low profile, compact design with ultra low profile thru-sheave becket and removable pin for Dyneema Link replacement. Features include lightweight construction, highest working load in its class, secure versatile attachment, low profile and compact design, ultra low profile thru-sheave becket, and self-lubricating Nylatron sheave for high dynamic loads. Applications: mainsheet and spinnaker sheets on dinghies to 5M (16'), halyard, vang and backstay applications on boats to 5M (16'), and control line applications on larger yachts.
