Garhauer Marine Cheek Blocks are designed to be fastened to a surface, such as a mast, using one side face rather than being suspended from a tang. These blocks are commonly used for guiding lines in various sailing applications, providing smooth and reliable operation. Built with durability in mind, they are ideal for use in environments where space is limited or where a more compact block setup is needed. As with all Garhauer Marine products, the Cheek Block comes backed by a 10-year guarantee, ensuring its long-lasting performance and reliability in harsh marine conditions.
