Seldén BBB 30 Triple Block fixed ball bearing with becket

The Seldén BBB 30 triple block with becket is a compact and lightweight triple block specifically designed for lower load applications on board smaller sailing yachts and as a trim line component on medium-sized vessels. This triple block features three sheaves running in parallel on stainless steel ball bearings, delivering exceptionally smooth and low-friction operation. The three sheaves provide a mechanical advantage of 3:1, making trimming and line handling significantly easier without requiring substantial physical effort.

The block body is manufactured from glass-fibre reinforced polyamide, a material offering an outstanding ratio between low mass and high strength. Weighing just 148 grams, this triple block is particularly suited for sailors who count every gram on board. The stainless steel ball bearings deliver the highest strength at lower dynamic loads, resulting in reliable and durable operation season after season. The safe working load is 600 kg and the breaking load reaches 1200 kg, more than sufficient for the forces encountered when trimming sails on smaller to medium-sized boats.

The fixed head enables direct attachment with a D-shackle or line. The integrated becket provides an additional attachment point, making this block exceptionally versatile across various rigging configurations. Whether you are building a fine-tune system, redirecting a halyard or setting up a sheet system with mechanical advantage, the Seldén BBB 30 triple block with becket delivers the dependable performance you expect from Seldén. The compact design fits effortlessly into tight spaces on board and accommodates lines with a diameter of Ø4 to 8 mm.
