Seldén BBB Single Block with Swivel – Ball Bearing

When dynamic loads are involved, every gram of reduced friction counts: The Seldén BBB block runs smoothly thanks to ball bearing technology, easing the strain on the line, your hand, and the winch. The integrated swivel ensures that the block freely follows the line's direction – without twisting, without jamming.

Tip: Regularly check that the sheave still rotates freely and thoroughly rinse the block with fresh water after sailing in salty areas – this significantly extends the lifespan of the ball bearings.
