The Seldén BBB20 is a fixed single block built around a 20mm sheave running on stainless steel ball bearings, giving smooth, low-friction movement on control lines that see regular use. Its glass fibre reinforced polyamide body keeps the block light without giving up strength, and the integral strap takes a shackle or a rope lashing depending on how it is being rigged. The becket adds a second attachment point, useful for building a simple purchase or anchoring a line end. Rated to a 150kg safe working load with a 300kg breaking load, it suits smaller boats and dinghies around Galway Bay and other Irish sailing waters where a compact ball bearing block earns its place on lighter-duty lines.
