The 29mm block from Harken, also known as the Carbo block is a lightweight, strong, reliable and affordable pulley block.
Harken 29mm blocks are popular on many sailing dinghies. 29mm carbo blocks are made with lightweight nylon resin side plates which replace the stainless steel straps found in other Harken blocks. Densely packed glass fibers reinforce the resin for strength.
The Harken 29mm block comes in various designs with these compact blocks having very high working loads for safe, easy trimming. You can expect breaking loads of up to 907kgs on some of these blocks.
