Triple Block Pulleys

A triple block gives you three sheaves in one housing, which is what you need when you are building a higher purchase system like a mainsheet, kicker or cascade and want to keep the load running smoothly. Pairing the right triple block with a matching becket and cleat lets you build a clean, efficient system that runs freely and holds when you need it to.

We stock triple blocks from Harken, Allen, Selden and Holt Nautos in sizes from 16mm up to 57mm, so you can match the block to your rope diameter and the loads it will carry. That includes lightweight Harken Air and Carbo blocks for dinghy control systems, higher load Zircon and ball bearing blocks for bigger boats, and versions with beckets, cam cleats and swivel heads so you can build the exact system your boat needs.

As dinghy sailors ourselves, we know a smooth, well specified block makes a purchase system easier to pull and quicker to adjust when it matters on the water. If you are not sure which size or which becket and cleat combination you need, call us on 01268 222912 and we will help you work it out. Order before 2pm Monday to Friday and we will ship in stock items the same day.
