The Seldén BBB 30 double block with fixed head and becket is a ball bearing double block specifically designed for purchase systems on smaller to mid-sized sailing boats. The two sheaves of this double block provide mechanical advantage when operating trim lines, sheets and other line routing aboard. The fixed head ensures a secure attachment point, while the integrated becket offers an additional fixing option for securing a standing part or creating a complete purchase system.

The stainless steel ball bearings of this Seldén BBB 30 double block guarantee exceptionally smooth operation, even under lower dynamic loads. The minimal friction makes this block particularly suitable for fine-tuning sail trim, where every bit of efficiency counts. The block sides are manufactured from glass fibre reinforced polyamide, offering a perfect combination of light weight and high strength. The central hole can also be used as a becket, providing even more configuration options when setting up more complex purchase systems.
