Introducing the Ronstan RF64108AW Series 60 Core Block Halyard with an Aluminium Sheave, designed for maximum versatility in a range of sailing applications. Featuring a screw pin and roller head, this block is engineered to provide exceptional performance and reliability. The aluminium sheave is designed to accommodate both wire and rope, offering adaptability for various rigging setups.

This halyard block boasts class-leading performance with a sophisticated design that enhances functionality and aesthetics. Its exceptional dynamic and static load performance ensures reliability in demanding conditions, providing peace of mind during both high-performance and recreational sailing.

With less than half the friction of its closest competitors, the RF64108AW Series 60 Core Block minimizes wear and tear on ropes and wires, ensuring smooth and efficient operation. The durable alloy rope/wire sheave is built to withstand the demands of harsh marine environments, ensuring long-term durability.

Designed for practicality, this block is ideal for direct attachment to a mainsail headboard in a 2:1 halyard setup. This feature enhances sail handling efficiency, especially during competitive or recreational sailing. The removable 8mm (5/16”) threaded pin at the head simplifies maintenance and customization, allowing the block to be tailored for different rigging configurations.

With an acetal roller on the head pin, this block also facilitates easy attachment with spliced lines, simplifying rigging tasks. The central hub hole serves as a becket take-off or tie-up point, increasing versatility and functionality.

Specifications for this block include a breaking load of 2000kg and a maximum working load of 1000kg, ensuring reliable performance under heavy loads. It can accommodate ropes up to 12mm in diameter, making it suitable for a variety of applications. Despite its impressive capabilities, it weighs just 212g, offering a balance of strength and lightweight construction.

Important Note: To achieve the full rated load of this block, the load must be uniformly distributed across the full length of the screw pin. A 14mm (9/16”) diameter mast collar post or a 14mm (9/16”) wide mast collar plate/tang is required for optimal performance and safety.
