40mm Single + Becket Block - Plain Bearing

Seldén 40mm Single + Becket Block - Plain Bearing (404-001-02R) is a single with becket plain-bearing block for yacht and dinghy control systems. The PBB40 uses an Acetal sheave and glass-fibre-reinforced composite cheeks for a strong, simple plain-bearing block. The stored specification lists 350 kg safe working load, 700 kg breaking load, maximum 8 mm line and 76.00 g weight. Select this version where the sheave count, becket, cleating or mounting arrangement matches the required purchase. When replacing an existing block, compare the Seldén article number and line/load requirements; for a new installation, ensure the attachment point is suitable for the expected working load.
