Seldén S30 Double Block fixed ball bearing tie-on

The Seldén S30 double block with tie-on attachment is a compact and lightweight block from the Seldén S-series, designed for trim lines and medium-duty applications on smaller to medium-sized sailing yachts. This double block features two acetal sheaves running on stainless steel ball bearings and is attached with a line or Dyneema loop. The S30 series offers an excellent combination of low weight, high load capacity and reliable operation, making it a popular choice among both racing and cruising sailors.

Weighing just 39 grams, the S30 double block offers an impressive safe working load of 200 kg and a breaking load of 450 kg. These specifications make the block suitable for a wide range of applications, from trim lines and cunninghams to lighter sheet applications. The acetal sheaves provide a smooth contact surface for the line, while the stainless steel ball bearings ensure minimal friction and a long service life. This results in smooth and efficient operation, even after prolonged use in marine conditions.

The tie-on attachment provides maximum flexibility when positioning the block on board. By attaching the block with a Dyneema loop or piece of line, you eliminate the weight of metal fittings and can quickly and easily mount or relocate the block. The S30 double block is ideal for racing dinghies, sporty cabin yachts and catamarans where weight savings and reliability go hand in hand. The two sheaves provide additional purchase, allowing you to exert more force with less effort.
