This triple block is designed for sailors who need stable and efficient line handling in compact purchase systems. It combines three sheaves with an integrated dogbone and cam cleat, providing secure holding and quick operation during trimming work. The design is based on a 2-stage ball bearing system that keeps friction low across the full load range. The through dogbone serves as a fixed attachment point, and the cam cleat allows precise adjustment with a secure grip on the line. This model is used in advanced control and trimming setups, including boom vangs, cunningham systems, and multi-line purchases. It works reliably with rope up to 8 mm and is suitable on both dinghies and sports boats. The lightweight construction and high capacity make the block ideal when both low weight and high strength are required. The three sheaves make it possible to distribute loads evenly and keep the trim stable under changing loads.

INSTRUCTIONS FOR USE Mount the block via the shackle at a fixed point. Lead the lines correctly through the sheaves and into the cam cleat. Avoid twisting and do not exceed the permitted load through the cleat
