Block & Tackle Systems

Ronstan manufacture a range of "block and tackle Systems" Ronstan manufacture a range of “block and tackle Systems” from small block and tackle selections to custom blocks and tackle for large projects.

Block Ranges:

Orbit Blocks™

The Ronstan Orbit Block™ Range are a no-compromise solution for suspension systems. The flexible Dyneema® Link technology comes from the latest trends in development. Meticulously engineered with an advanced fibre and polymer technology they are up to ten times stronger than steel whilst being lighter and more compact.

In our orbit block range we have a specialist project called a Lashing Orbit Block™. These have extremely high breaking loads for their size and weight. They were developed to meet the demands and expectations of the very dedicated and increasingly professional racing sailor, they are now transposing into the Industrial world for applications requiring the highest quality industrial block.
