20mm Single Strap Block - Plain Bearing

Seldén 20mm Single Strap Block - Plain Bearing (402-001-01R) is a single strap-mounted plain-bearing block for yacht and dinghy control systems. The compact PBB20 uses an Acetal sheave and stiff glass-fibre-reinforced cheeks to reduce the risk of the line wedging. The stored specification lists 70 kg safe working load, 140 kg breaking load, maximum 6 mm line and 7.00 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.
