Product Description

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. Features through-hub mounting for maximum strength and can be stacked to create a double (total block load same as single, maximum load on top sheave not to exceed 50% of total block load).

• 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.
• Stackable to create double version.
• Removable cover plate.
• Fully machined Alloy cheek plates.
• Alloy sheaves with captive ball races.
• Forged grade 17-4PH stainless steel shackles.
• Grade 316 stainless steel head post.
