Seldén BBB 20 Triple Block fixed ball bearing with becket and cam cleat

The Seldén BBB 20 triple block with becket and cam cleat is the most versatile block in the BBB 20 series, combining three sheaves with an integrated cam cleat and becket in one compact package. This triple block is designed for sailors who demand maximum functionality in the lightest possible design. The three parallel sheaves provide the highest mechanical advantage within the BBB 20 series, while the cam cleat makes it possible to lock the line instantly without having to mount a separate cleat.

The integrated cam cleat in this Seldén BBB 20 triple block is a particularly valuable feature for applications where the line needs to be quickly cleated and released, such as when operating trim lines and sheets on smaller sailing boats. The becket provides an additional attachment point for the standing end of the tackle, allowing the block to be used directly as the terminal block of a complete purchase system. The stainless steel ball bearings guarantee smooth, low-friction operation across all three sheaves, which is essential for efficient power transmission.

The block body is manufactured from glass-fibre reinforced polyamide, a material that combines light weight with high strength and durability. With a safe working load of 300 kg and a breaking load of 600 kg, this triple block is engineered to handle the forces encountered while sailing in varying conditions. The weight of 174 grams is remarkably low for a triple block with integrated cam cleat and becket. The fixed head allows attachment with a shackle or line, enabling the block to be mounted at various positions on board. Whether you are rigging a dinghy, catamaran or small cruiser, this all-in-one block considerably simplifies your rigging layout.
