Seldén BBB 20 Triple Block fixed ball bearing with becket

The Seldén BBB 20 triple block with becket is the extended version of the popular BBB 20 triple block, specifically fitted with an additional attachment point for securing the standing end of a tackle. This triple block features three sheaves running on stainless steel ball bearings, offering maximum mechanical advantage for light-wind applications and complex purchase systems on smaller sailing boats. The integrated becket allows the standing end of the line to be attached directly to the block, which considerably simplifies building a complete purchase system.

The stainless steel ball bearings guarantee an exceptionally smooth and low-friction operation, which is essential in triple blocks where the line runs over multiple sheaves. The block body is manufactured from glass-fibre reinforced polyamide, a material that excels in combining low weight with high strength. Weighing just 113 grams, this triple block adds barely any extra weight to your rigging whilst still offering a considerable load reduction when operating sheets and trim lines. The safe working load of 300 kg and breaking load of 600 kg make this block suitable for a wide range of applications on dinghies, catamarans and small cruising yachts.

The fixed head provides solid attachment options with a D-shackle or line, while the becket holds the standing end of the tackle in place. This makes the Seldén BBB 20 triple block with becket the ideal choice for building complete purchase systems, for example for the mainsheet, backstay system or cunningham system. Whether you are cruising or racing, this triple block delivers the dependable performance you expect from Seldén, combined with the flexibility that a becket provides when configuring your rigging layout.
