Seldén PBB 70 Single Block – Plain Bearing Block for Very High Loads

The Seldén PBB 70 single block is the heaviest block in the Seldén PBB series and is designed for very high working loads on larger sailboats. With an impressive safe working load of 1500 kg and a breaking strength of 3000 kg, this block is engineered for the most demanding tasks on board, such as mainsheets, halyards and backstay systems.
