Product Description
Ronstan Series 60 Single Halyard Orbit Block
Product Information
Orbit blocks™ are a no-compromise product range developed to meet the demands and expectation of the very dedicated and increasingly professional racing sailor. Side cheeks incorporating head structure and hub are precision machined as a single part from solid alloy, leaving material only where it contributes to the load carrying capacity of the block and eliminating the need for additional fasteners. The Orbit sheave has captive Acetal ball bearings for side thrust loads, eliminating the need for side retainer plates. This reduces weight and allows for a wider bearing surface that can accommodate longer Torlon® needles – achieving a substantially higher strength-to-weight ratio. Halyard blocks are used in applications with a fixed line entry-angle to keep lines close to the deck as they lead aft to organisers and winches. Halyard block has a removable pin for attachment to deck padeyes or mast collar.
Features
The highest strength-to-weight ratio
Minimal friction loss, especially when working at high loads
Totally reliable and trouble free performance
Simplicity of design and construction to facilitate maintenance and servicing
Elegant, functional styling and finish.
