Seldén BBB 30 Single Block with Tie-On – Ball Bearing Tie-On Block

The Seldén BBB 30 single block with tie-on attachment is a lightweight ball bearing block from the Seldén BBB series that is secured with a line (tie on). This design contributes to minimal weight and offers maximum flexibility during installation. The block is suitable for light to medium loads on smaller and medium-sized sailboats.

The stainless steel ball bearings guarantee the highest strength under dynamic loading, while the glass-fibre reinforced polyamide frame ensures a durable and lightweight construction. The tie-on attachment allows the block to be secured at any desired position without drilling into the deck.
