Seldén BBB 30 Double Block fixed

The Seldén BBB 30 double block with fixed head is a versatile ball bearing block for lower loads on smaller to mid-sized sailing boats. This double block features two sheaves, making it excellently suited for purchase systems, sheet redirections and other line routing where mechanical advantage is required. The fixed head provides a solid attachment point that can be connected with a shackle or line.

The stainless steel ball bearings of this Seldén BBB 30 double block deliver exceptionally smooth and reliable operation, even under lower dynamic loads. This makes the block ideal for trim lines, vang systems and other applications where consistent, low friction makes the difference in sailing performance. The glass fibre reinforced polyamide block sides offer an optimal balance between weight and strength. A notable feature of this block is that the central hole can also be used as a becket, providing extra flexibility when setting up purchase systems.

With an impressive breaking strength of 800 kg and a safe working load of 400 kg, the Seldén BBB 30 double block performs well above its weight class. At just 97 grams, this is one of the most powerful blocks per gram on the market. Whether you are setting up a trim tackle for the mainsail cunningham, configuring a vang system or redirecting sheet lines, this double block consistently delivers reliable performance. Its suitability for lines from Ø4 to 8 mm makes it applicable across a wide range of boats and rigging configurations.
