Harken Pulley Blocks

Shop the full range of Harken pulley blocks at Fox's Chandlery, a UK Harken stockist. Harken blocks set the standard for low-friction sail handling, and this collection covers every size and application: 16mm dinghy blocks and Micro blocks for control lines, the hugely popular Carbo Air range in 29mm to 75mm, T2 soft-attach fly blocks for high-tech line applications, and robust Element blocks for cruising loads.

Choose singles, doubles, triples, fiddles, ratchets and blocks with beckets to build any purchase system. Harken's free-rolling ball bearing and bushed designs mean less effort at the sheet and longer hardware life. If you're unsure which block suits your line diameter and working load, our riggers can help you specify the right part.

Frequently asked questions

How do I choose the right size Harken block?

Match the block to your line diameter and expected working load - each Harken block lists a maximum line size and safe working load. As a rule, pick the smallest, lightest block that comfortably exceeds the loads in your system.

What is the difference between Harken Carbo and Element blocks?

Carbo blocks are lightweight, high-performance blocks ideal for dinghies and race boats, while Element blocks use a forged aluminium body for durable, cost-effective handling of cruising loads.

What are soft-attach blocks?

Soft-attach blocks like the Harken T2 lash directly to fittings with high-strength line instead of a metal shackle, saving weight, reducing noise and allowing the block to align perfectly with the load.
