Description

The Ronstan Series 75 Strop Orbit Block, Double #RF79209 is a high-performance sailing essential designed with the dedicated racing sailor in mind. This block is engineered from solid alloy, ensuring only the necessary material is used for optimal load capacity, making it lightweight yet robust. Its unique design includes acetal ball bearings for efficient side thrust management, enhancing its strength-to-weight ratio.

Constructed with fully machined alloy cheek plates and alloy sheaves featuring captive ball races, this block is built to withstand demanding sailing conditions. The carbon black acetal ball bearings provide a wider bearing surface, suitable for longer Torlon® needles, ensuring exceptional performance. This product is compatible with various sailing systems, including mainsheet, halyard, and spinnaker setups on boats up to 14m (46ft), and more general control line usage on larger yachts.

Usage

Ideal for primary mainsheet and halyard systems on mid-sized boats, this block is also suitable for secondary mainsheet and vang blocks on larger vessels. It excels in standard and running backstay applications, providing reliable performance in diverse sailing scenarios.
