Rutgerson Triple Block with Jammer – Plain Bearing Block for High Loads

Three sheaves, an integrated cleat – and maximum power reserves where it counts. The Rutgerson triple-sheave block combines proven plain bearing technology with a directly mounted cleat, making it perfect for all control points where you want to quickly secure a line. High-strength composite material in the sides and sheaves ensures low friction and a long service life on board.

Tip: When purchasing, pay attention to the correct rope dimension – a sheave diameter that is too small increases wear on the rope. When in doubt, choose one series larger.
