A triple block is used in purchase and trim systems where you need to lead multiple lines through the same block, or where you want a high mechanical advantage. It is relevant for both cruising and racing sailors working with advanced trim, sheet purchases or control systems. It gives you stable and controlled line lead, even under changing loads on board. The block works with three sheaves, which distribute the load and provide better purchase. The design is typically based on composite side plates and sheaves with plain bearings or a ball bearing, depending on the model. This gives smooth rotation and predictable operation, even when the line is loaded. A swivel function may be available on some models and provides free movement when the rig changes direction dynamically. The triple block is used in systems for trim, sheets, purchases, fine-tuning and control of multiple lines combined. It can be part of purchases on the boom, mast or deck-mounted systems. Models with a becket or dog can expand the range of applications, depending on the boat's setup. It works with most common rope diameters on board and typically fits both cruising and racing rigs. A triple block delivers high functionality in limited space because three sheaves are combined into one unit. It is an excellent choice for sailors who want to optimise their trim and create a more precise purchase system. On boats with heavy mainsheets or advanced control lines, the triple block provides a lower, more controlled pull. A 360° rotation on certain models makes manoeuvres easier, especially when the boat requires frequent adjustments.

Shackle pin Ø: 5 mm

INSTRUCTIONS FOR USE Preparation: Choose a mounting point and make sure the block type matches the rig's load and line selection.

Installation: 1 Installation is typically via shackle or swivel head, depending on the model. 2 Lead the lines through the three sheaves in the correct order according to the purchase plan. 3 Lightly tension and check that the sheaves move freely.

After use: Rinse the block in fresh water after sailing and check the sheaves and any cam-cleats for wear.
