The name of the Ronstan SHOCK Block is derived from SHeaveless blOCK and reflects the growing trend for replacing ball bearing blocks, with “low friction rings”, in a whole range of sailing system applications. Lightweight, high-load with no moving parts, Shock blocks are perfect for control lines and small purchase systems.
Made of anodised aluminium, Ronstan Shocks are available in two sizes (for lines up to 5mm and 10mm max diameters) and 3 colour options (Blue, Red and Grey). They are specifically designed for soft attachment; either spliced directly onto the end of a line, lashed or fixed in place with webbing.
