This triple block is used in purchase and trimming functions where you want high mechanical advantage and stable line lead. It is relevant for sailors working with mainsheet purchase, fine trim, or other systems where three sheaves provide an easier pull and better control. The block provides a reliable turning point and is used in both cruising and racing setups. The block is constructed with three composite sheaves and operates with a plain bearing or spherical plain bearing depending on the model. This provides smooth and stable rotation under load. The design ensures low friction and robust operation in a marine environment. Some models have 360° rotation so the block can follow the movement of the line dynamically. The triple block is used in purchases, mainsheet systems, barber haulers, fine trim, and other control points. It can be combined with single blocks, double blocks, or blocks with becket in larger systems. It works with common rope sizes on board and can be retrofitted without major changes to the existing rig. With three sheaves combined in one compact unit, you get both good purchase and flexible line lead. The block is suitable for both smaller and medium-sized boats where optimizing trim and control is important. Models with a swivel head provide extra freedom of movement during manoeuvres.

Shackle pin Ø: 8 mm

INSTRUCTIONS Preparation: Choose the mounting point and make sure the block can move freely.

Installation: 1 Mount the triple block with a shackle or suitable fitting. 2 Lead the line through the sheaves according to the desired purchase. 2 Tension lightly and check for free rotation.

After use: Rinse the block in fresh water and check the sheaves for free running.
