The Seldén BBB 25 triple block with D-shackle is a powerful and compact three-sheave block from the renowned BBB series (Ball Bearing Block). Featuring three sheaves, this block provides a significant mechanical advantage, allowing you to transmit large forces through your purchase system with minimal effort. The D-shackle ensures a quick and reliable attachment to sheets, halyards or other rigging components. With a safe working load of 400 kg and a breaking strength of 800 kg, this triple block handles serious dynamic loads despite its remarkably low weight of just 50 grams.

The construction of the BBB 25 triple block is characterised by stainless steel cheeks that deliver exceptional strength and rigidity, even under the harshest conditions at sea. Each of the three sheaves rotates on a row of high-quality stainless steel ball bearings, reducing friction to an absolute minimum. This means lines run smoothly and effortlessly through the block, even under heavy load. The adjustable rigging pin makes it straightforward to mount and remove the block during maintenance or seasonal work on your boat.

This triple block is ideally suited for purchase systems on smaller sailing yachts, sportboats and daysailers where a high mechanical advantage is required. Combined with a single or double block, you can easily build a 4:1, 5:1 or even 6:1 purchase system for cunninghams, vangs, kickers or fine trim lines. The block accepts lines from Ø1 to 5 mm, perfect for modern thin Dyneema and Spectra lines that are increasingly popular on racing and cruising yachts. The fixed attachment provides stable positioning, ideal for applications where the block needs to remain in a set position.
